Octoprint embedded into OrcaSlicer - asks everytime for credentials (or worse)

What is the problem?

I've embedded OctoPrint into OrcaSlicer. It works - almost.
Everytime I rerun OrcaSlicer I have tu put my credentials (user/password) into OctoPrints login screen, even If "Remember Me" Checkbox is checked.
So, If I start OrcaSlicer, go to Device and login to OctoPrint and go back do Orcaslicer to proceed further - everything will go smoothly, GCODe will be correctly uploaded etc. Without logging in I'll just see login screen.
But! There is one more issue in the same place: If I start Orcaslicer from Freecad (there is Macro for that) STL file will be exported smoothly from freecad, imported successfully to OrcaSlicer, but, OctoPrint even do not show login screen, just and only blank site.

So:

-> OrcaSlicer started manually -> always need to login to OctoPrint
-> OrcaSlicer started by Freecad -> blank page instead of login screen.

What did you already try to solve it?

I tried to re-generate API keys for OctoPrint, but no efect

Have you tried running in safe mode?

Yes

Did running in safe mode solve the problem?

No, it is worse - login screen does not appear even in Orca started manually.

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)
