Sessions problems on CI4

Hi, I have on my localhost with xampp on windows 11 several ci4 installations.
They worked fine until two days ago, because suddenly I could not open them anymore because I always receive this error message:

CodeIgniter\Session\Exceptions\SessionException
Session: Configured save path "D:\xampp\apps\prototype\writable\session" is not writable by the PHP process.

Of course I checked the folder permissions and they are properly assigned, considering no one has touched them,
and also I've checked the line

Code:

public string $sessionSavePath = WRITEPATH . 'session';

on App config file.

The only thing I've made, was to synchronize the xampp folder on Google Drive, maybe that changed something.

Is there someone who already faced this issue?
It doesn't seem to be a permission problem.
Maybe xampp installation went broke...

Thank you!

when there are "certain changes" that are not wanted on linux we use "timeshift" to revert ( it basically uses rsync ) on Windows can you not use " restore" to go back to when it worked.

I use Arch Linux by the way

Hi, that was a good idea and I tried it right now, but it didn't work.
I don't understand...

Thank you anyway
