When I try to open Photoshop 2021 in MacOs Big Sur, it completely freezes at "extension...halide bottlenecks". Sometimes it freezes at "extension...multiprocessorSupport". I've tried searching for others with this problem, tried fixing it, but all the solutions seem sooo complicated. Please help!

Hi,

 

We're sorry about the trouble while launching Photoshop 2021. Please try the steps suggested here: https://helpx.adobe.com/photoshop/kb/freeze-on-launch.html

Also, please try validating the fonts installed in the Font book of your Mac & remove the corrupt fonts. You can check out the steps suggested here: https://www.howtogeek.com/405240/how-to-validate-and-remove-fonts-on-a-mac/

 

If the issue persist, you can try to reset the preferences of Photoshop manually using the steps mentioned here: https://adobe.ly/3dFRlyi

Please backup your settings prior to resetting the preferences. You can check: https://adobe.ly/2vNz6FG

 

Let us know how it goes!

Regards,

Nikunj

Thanks for your help, but I just tried everything you suggested, step by step, and the problem still hasn't been fixed. Photoshop still completely freezes at the startup page.

Is there anything else I can try? Like I said, I followed all of those suggestions and I still cannot open Photoshop at all.
