I have an issue as well and it is ONLY in the last week when illustrator updated. I was a few patches old prior to that and did not have the issue. It's not just scrolling that does it. I can just cut something (ctrl-x) and it freezes up illustrator. Or delete something in illustrator. Small art or even just a date in text. Freeses up illustrator. It's only been since end of last week (Thursday/Friday).
First I tried a clean install of graphics drivers (used DDU to completely remove GeForce drivers). Then I used a windows registry cleaner. Those to things changed nothing, illustrator still freezes up. Sometime after 5-10 minutes. Sometimes almost right away. Next I tried using Creative Cloud repair tool and completely removed ALL of adobe products and ran the repair/cleaner. Restarted windows, and then reinstalled everything adobe again. Same thing, illustrator still freezes.
Desparate, I wiped the entire C: drive, reinstalled Win 11 from scratch, then just drivers and illustrator... worked for a couple hours but then froze up when scrolling. I have zero issues with any other adobe product crashing (mostly Other than illustrator mainly, I also use photoshop and acrobat). I also have no other issues with any other software. Only illustrator is often and regularly hanging (just stops working and spinning cursor).
I have removed illustrator and reinstalled a version two older hoping that MAYBE this is something introduced in the most recent patch or two. I'm running 27.5 now and it has not froze up for a few hours. Fingers crossed.
I have a i9-12900k cpu on a solid Asus ROG Strix MoBo and 64 gb of RAM that is on their QVL list. Paired with an MSI 3090 nVidia GPU (a freaking monster) with a Platium Plus 1000w Corsair power supply (HX1000). I spair no expense when I build my systems for work or play. And like I said, this PC works excellent doing everything else. Only illustrator is hanging and it all started w/ the most recent update. I should ahve realized it before going through all the trouble I did and reverted to an older version... but only time will tell if that is really the problem.
I'll update this thread as I work in illustrator in the coming days.
