Hello! I'm having an error trying to run a script that uses PySide6:

qt.qpa.plugin: Could not find the Qt platform plugin "windows" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

I've read about this bug in some foruns (stackoverflow and here, basically) and I've tried to run some debug that I've read there:

running echo %QT_PLUGIN_PATH% returns just %QT_PLUGIN_PATH%;
I tried to download the ListDlls program, but I don't know which executable should be searched for in this case (I've tried python, but it didn't yield any results).
I've checked env variables for Qt related things, but found nothing;
I've searched the whole C:\ for qwindows.dll files, I found at least 10 of them, but I don't know if I can just erase the recent added ones or which one I can erase;
$Search in the C:\ disk$
I've tried to reinstall both Python and Anaconda, to no success;
I even tried to add one of the qwindows.dll location as a env variable QT_QPA_PLATFORM_PLUGIN_PATH even though people disprove it, to no success.

And don't know what else to do... I'm thinking about a full reboot in my computer at this point. Any thoughts?
