When Lightroom is running in the background I am experiencing a lag when opening files in Illustrator. It takes about 40 seconds for the file to come up in Illustrator, even with smallest files.

Had this issue for a long time now and with X versions of Illustrator in the past.

• Keep lightroom running parallel to illustrator
• Open File (double click or from the menu)
• Blank file pops up and stays freezed for an amound of seconds

• File opens completely

• PC, Windows 10 pro 21H2, last X Versions of Illustrator

More strange: When I send Lightroom to a systray icon with third party tools, so no icon is visible in the taskbar, the lag is gone!
Also, when the file opening hangs and I switch to Lightroom for a second and then back to Illustrator, the file pops up (it ends the freezing).
