After updating latest CC Illustrator update my mouse no longer can drag objects i can only use the arrow keys to do this. It was working fine yesterday. Work fine in any other programme such PS, Ms PPT.

Adobe Illustrator CC 2019 is not able to generate PDF-compatible files

No matter what I do (re-save as a AI, EPS, PDF, check/uncheck 'create PDF compatible file', etc...), if I save as a PDF, the PDF will show up saying "This is an Adobe Illustrator File that was saved without PDF content" etc... Is this a version 2019 bug???

Illustrator freezes or crashes 1 to 2 times a day. I use it for 8 hours a day at work. When it freezes, I have to force quit with Task Manager. I'm using 2020, and I had this exact issue with 2019. However with 2020, whenever it freezes and I force quit, once I open Illustrator again all of my preferences are back to default. These preferences include: custom Keyboard Shortcuts, the workspace, boxes that have been checked (e.g. the Preview box in Envelope Distort).

Positive: when it does crash files are recovered,
negative it does crash often... at least once or twice per day.

My issues with illustrator 2019 started with previous update, but I'm running Windows 10 Pro 1903 and it's still a problem. Seems I've been lucky though to have this only happen to me recently. People have been raising their hands on this being an issue for them since October 2018! Unbelievable. So what's the solution?

The platform is: Illustrator 23.0.6 64-bit, on Win10 Enterprise 1903 latest updates, and with nVidia drivers R430 U5 (431.70).

The bug is that Illustrator freezes for ~5 seconds after/during a simple copy command, and "Not Responding" is displayed on the top title bar. This can be induced by just opening a new file, drawing a rectangle, then trying to copy it (with Ctrl-C or with the menu command).

This is destroying my workflow...

Every time I drag a color swatch, whether an existing swatch or eye-dropped, into my gradient panel, Illustrator crashes. I'm also having issues with my gradient sliders spazzing out when trying to drag them. It causes my program to freeze up. I have one file open and only five gradients in my file, so not enough to overload illustrator. It's making my job extremely hard to do. I have also restarted and tried re-installing illustrator.

Major issue with Blob Brush lagging (if using either mouse OR tablet). When using Blob brush on earlier versions, no lag at all.

Illustrator is chewing up every mb of memory of my computer until it then crashes. nothing else is open on my computer. no files are open with illustrator itself. yet its memory usage grows from 0-40gb then the program crashes due to lack of memory. ive clicked the repair bug button it pops up with. ive un installed and re in stalled. creative cloud did some update and install. ive turned my computer off and on. nothing fixes it.

Pathfinder join is no longer working, it will group the items but will not make 1 single shape, or compound path

I'm using an iMac with Mojave 10.14 and Illustrator 23.0.1.

I'm getting a crash while recording an action with a grouped object selected, I try to edit a transparency via the Properties menu. The crash is within one to two seconds of hitting enter on this change, consistently. Seems like it's another part of the memory leak that's happening?

I'm rolling back to 22.1 until this is resolved.

Since the Oct 2018 update, I cannot open or use the program. I see this screen (see attached). Also, I'm not sure if this has anything to do with the issue, but since the update a folder has appeared on my desktop named 'GPUCache' with 5 files inside (photo attached)

After using Illustrator 21.1 for a period of time - usually over 20 minutes - the software becomes increasingly slow, laggy, unresponsive. Quitting and restarting Illustrator fixes this, but it then happens again. And again.
I have tried using fresh preferences: it makes no difference.
PC system is Intel i5-7600K @ 3.80GHz, 16GB RAM, nVidia GTX 1050Ti, up-to-date drivers, up-to-date Windows 10.

For some reason the arrow keys stopped working after the lastest upgrade. arrrrgh… I cannot use the up/down arrow keys to nudge artwork anymore. My workaround is to open the transform tool/panel, and play with the “X” or “Y” numbers to get a little “nudge”… so annoying! The only thing that changed on my end was that I updated the Illustrator software recently, so thinking this is an Adobe issue and not user error. Can you please fix this?

There is some kind of problem with the text spacing feature. It has been causing issues such as duplication of previous text, deleting text from another part of the page, causing all text to be spaced incorrectly and more.

When I open the program, everything is going and moving fast, after awhile it gets really slow!
I understand that it maybe after awhile the cache gets full and the program gets to operate slower but this is not the case here.
With previous versions I didn't have to close and open the program in order for it to speed up. I would go for weeks not needing to close it. Right now in just couple of hours the program works from fast to being slow for no reason.
