@CShubert did you miss this bit

I now just found out that the problem is the .png file. The files I did try to open today were all produced by Microsoft Teams. I downloaded them from a chat. I now just had the idea to try withsome other .png's and they all work fine. Sorry for the inconvinence I caused. Could have tried that earlier.

Hi @Stilcreator sorry to hear this.

Let's make sure we're in a default state and there are no stale settings somewhere: 

Restore your preferences using this manual method:

Does it work correctly? 

If that doesn't solve it, you can quit Photoshop and put the Settings folder back. 

It may help if we could see your Photoshop System Info. Launch Photoshop, and select Help >System Info...and copy/paste the text in a reply.  

Thank you,

Cory

Hi, can you try to upload and share it to your creative cloud storage room, then share a link here?

There is no inconvenience at all! Sorry if our tone sounded like it.

I meant in Photoshop's help>System info menu...

Hi both,

for system information the only thing I could find was Windows 10 Enterprise, 21H2, does that help?

I did reset the preference settings but the same happened. Photoshop froze. And it didn't show up in the Task manager anymore. So I tried with escape button. That worked so far that it unfroze the app so I could close it or try again but the outcome is still the same.

I wanted to upload  an image as example, but that didn't work either. 

Hi, and Welcome, @Stilcreator . As the updates do not replicate all over the globe, please make sure to give the version number that you are using, check in Help>System info.

This way, in the future, users can know the version that might have an issue.

I'd wait for your message once you've moved the preferences files, if it did fix your issue.

Hi

No issues here opening any file formats including png's, using Photoshop version 24.1.1 on Windows 10.

Try manually resetting your Photoshop preferences
