A "popular" issue is, that people use an extension, which renames files saved by Photopea to .TXT. It is reported several times a week and every time, I tell people to disable an extension. They often argue, that it can not be caused by an extension, or even lie, that they disabled it and it did not help.
"Google docs offline" is an official extension from google which you get prompted to install when you go to Google Drive in Chrome without the extension installed. I don't think that caused anything and it looks like there was an actual bug you had:
> There really was a bug in Photopea. If you opened a file, whose name started with a dot . , like .myfile.psd, It was always exported as .TXT_
> I have fixed this bug. You can open files with any names now, and they should be saved under the right extension.

It did seem like the issue was on your end and not the extensions though.
