Unable to drag objects
I have come across this several times now. Unable to reproduce, but periodically you lose the ability to drag objects in Illustrator. You can rotate, nudge and use manual transform tools, but can't left-click + drag. The only way to resolve it is to restart the machine (not just Illustrator). A nuisance! Build 23.0.2 Win 10 64.
Please accept my sincere apology for the inconvenience. Please get in touch with us at any of the other support channels – https://helpx.adobe.com/support.html . Since this is not a generic issue that we can reproduce at our end, we will need someone to look into your machine to figure out what is going on here.

I'm having this issue with build 24.0.2 on Win 10. I can select the object, move it with arrow keys, rotate it with the mouse, but when I try to drag it, I get an error sound and no movement.
Also having this issue very frequently. When trying to drag objects (have this issue most often with stroked lines), Illustrator will try and marquee select instead of moving the object (even though AI shows the free transform icon next to the cursor).
