my photoshop auto reset all settings and preferences every time I leave and come back.

I see that you use Illustrator and Premiere Pro as well, one can only assume that they are pirated/illegal copies as well. You should give this a read

ok

You're using Photoshop as a trial version

Adobe Photoshop Version: 21.0.3 20200115.r.91 2020/01/15: 21f283574f6 x64

The only version of Photoshop available for the trail is version 21.2.2

License Type: Tryout Version

Version 21.0.3 was released in January so you must be using a Pirated/illegal version

That's very odd. Have you tried reinstalling Photoshop, and if that doesn't work uninstall,  use the Creative Cloud cleaner, then reinstall? 

You may want to check for permissions issues.
