Not sure what to do now. I talked with support and ran the Creative Cloud cleaner, reinstalled everything, it opened once, now I'm back to it not opening.
I rolled back to the previous version yesterday, then updated, and it was working fine. Today I installed two previous versions, but neither of those worked either, even after updating. That's when I talked to support. My new machine at work is less than 2 months old, has plenty of RAM and hard drive space.
Windows 10 Pro. I'll let you know how the new user account goes. Thanks.
I am experiencing the same problem. Illustrator isn't working. every time i try open it, I have recently updated to big sur ios, also recently updated to illustartor 2021 and ever since illustrator doesnt run. all other programs do.
