Can not open eny formats files in PS2021 after camera raw

There is a known issue some people are experiencing with RAW files after loading the new version. I do believe that Adobe has posted an ACR upgrade, so please make sure everything is up to date.

Sorry can't read the error message you posted but if it's this "Could not complete this operation because of a Program Error"

Then it's a known issue
