Logged out & settings reset to default each time app is launched

Dell laptop

Debian 12.9 amd64

Zoom Workplace 6.3.6

SSO sign-in (Okta)

Every time I quit the app and restart it, I am met with a Zoom login prompt and my Settings are reset to default, even though I check the box on the login screen to keep me signed in. As for settings, all are reset to default each time I launch the app and log in.

For example, I can set the following:

General : Ask me to confirm when I leave a meeting: no

Video : Original ratio: yes, HD: yes, Mirror my video: no, Turn off my video when joining meeting: yes

Audio : Automatically join audio by computer when joining a meeting: yes

Team Chat : Show my status as Away when I am inactive for __ minutes: no

I close the settings window and these preferences are preserved for days and through multiple meetings, as long as I leave Zoom running. I can even sign out and back in, and settings are preserved as long as I didn't quit the app. But if I close Zoom and reopen the app, I have to sign in again and all of these settings are back to default. Is this expected behaviour? I don't think so, but I don't know how to correct it so that I can stay signed in and my settings are preserved across multiple launches of the app.
