Hi there,
Sorry to hear that Photoshop 2021 latest version has multiple issues.
Would you mind explaining the problems you're facing with the new version?
Also, we have released a new version 22.4.1 which fixed the issues in 22.4 version.
To know more about the update, please checkout this documentation: https://helpx.adobe.com/photoshop/kb/fixed-issues.html
Thanks,
