Illustrator freeze at launch after opening an old version file

[default3nipfc5necxc]

Hi everyone.   I recently updated it to 26.0.3 and It worked fine but after opening the file it started freezing for no reason. I don't know why and it always pops up com.AdobeSplashKit.GraphicWindowClass. But when I use administrator to open Illustrator, It works and runs as smoothly as butter.

Have tried the following and nothing works.

• Updated GPU Drive 
• Restarted Computer
• Changed AppData\Roaming\Adobe\Adobe Illustrator 26 Settings to Adobe Illustrator 26 Settings_old
• Reinstalled and uninstalled 
• Used Adobe Creative Cloud Cleaner tool

Honestly frustrated and really do not know what's left to do. Please help me.

Hello @default3nipfc5necxc,

Sorry to hear about this experience. I would request you try running Illustrator under a different administrator account and check if it helps.

Also, try updating Illustrator to the latest version and share your observations.

Looking forward to your response.

Thanks,

Anubhav

Hi @Anubhav Majumder 

I just open a different administrator account and it works! I get to use it for a while and I went back to my previous account. With curiosity, I tried to open Illustrator once more and It opens!!!! Everything works fine and might test to open the older version file again and see if its works or not.

I'm so happy about it and Huge Thanks for your advice, Thank you very much!
