Zoom on Linux hangs at startup

[zevv]

Launching zoom from the command line with `/usr/bin/zoom`, nothing at all happens.

- Debian 12

- Pipewire (not sure if relevant)

- Zoom Version 5.15.5 (5603) / 5.9.6(2225)

Messages below end up in the logs. After this, no more messages are emitted, the process and its subprocesses still run, but no window appears. strace shows a lot of system calls still happening in multiple processes, but I'm not able to deduce any root cause from this.

I already found these threads, but the solution/workaround offered does not solve my problem:

- https://community.zoom.com/t5/Meetings/Zoom-5-10-4-Linux-client-does-not-start/m-p/60220

Any hints on how to debug this further very much appreciated.
