Bug: Meeting window does not open after joining on Ubuntu

Hi,

i installed the latest version 6.4.13 (2309) on 2 Ubuntu systems:

1. a Classical Ubuntu

2. Linux Mint, which is also Ubuntu-based

On both systems i experience the same poblems.

Also on the first system i tried an older version (don't remember the version number), but it was the stable release version from snap.

Reproduction:

- start an Ubuntu system

- open zoom

- press "join a meeting"

- enter ID

- enter PWD

- accept conditions/policies

- nothing happens - the main window stays unchanged, the "join a meeting link" is disabled, no meeting window appears

- when closing the app now a confirm window opens "Are you sure to leave the meeting?" with "Leave" and "Cancel" buttons.

Both systems are fully updated.

Freshly restarted.

Zoom fresh installed.

The meeting was already in progress - it was possible to connect with other devices.

Same happens with Test-Meeting: https://zoom.us/de/test

This looks like a real bug.

Greetings Fino
