I deinstalled the new version and went back to 22.43 after one day because I had more crashes than I usally have in a year^^.
Would be interesting to get an idea if it's my problem only (than I have to check my system) or if it's also happening to other users more often than usual. (My main System: Win10 / 64 GB Ram/i7/ GeForce GTX/
Yes your software is all updated but Photoshop 2021 is not all updated. https://helpx.adobe.com/photoshop/kb/known-issues.html Adobe is working on many known issues in Photoshop 2021. Adobe is updating Photoshop Graphics feature to use newer modern API. When Adobe addresses all the known issues in Photoshop 2021 it should be a better Photoshop version than prior versions of Photoshop. Till then you should use Photoshop 2020 to do your editing or at least have Photoshop 2020 installed in case you run into a Photoshop 2021 issue. You can Photoshop 2020. However, if the issue is in a new Photoshop 2021 feature only Adobe can address the issue. Why did you step to a previous version with known issues. All Photoshop 22.x versions have known issues. Use Photoshop 2020 when when you run into an issue in the Photoshop 2021 version you have installed. Just keep installing Photoshop 22 updates Adobe is addressing issues in Photoshop 2021. Adobe also seem to be maintaining Photoshop 2020. So I also have Photoshop2019 installed I can fall back to.
