Ever since I'vew updated my Adobe PR Pro to the 2021 version I've been having issues!! Its Slower, the video flickers. My CPU is sending me ERRORS for every single add on. I didn't have any issues with the last version before the update at ALL. Any way to fix this problem? Or anyway to go back to the 2020 version?
You can have mulitple major versions installed at any one time. I NEVER have it remove the prior version when adding a new ... a version being say 14.x to 15.x. That is set in the Preferences of the Creative Cloud Desktop app.
From the CC Desktop app, select the All Apps tab, then scroll down to the current PrPro. Click the three dots to the far left, and choose "Other Versions". You can scroll back through both the minor updates of 15.x or even back to 14.x.
