Ubuntu: Can't join meeting with version >= 6.4.0

Hi,

I am having troubles to join a meeting on Ubuntu with a version larger than 6.3.11 (7212).

The connection to the meeting works fine, but after following the link or enter meeting ID and passcode nothing happens. Nothing in the logs, no hidden window or process.

It was a bit tricky, but I managed to install download and install 6.3.11 (7212). Version 6.3.0 is currently the minimum required version.

https://cdn.zoom.us/prod/6.3.11.7212/zoom_amd64.deb

Setup:

- Dell Latitude E5550 (Intel Core i5-5300U)

- kernel 6.14.0-33-generic #33~24.04.1-Ubuntu

- KDE plasma 6

- xdg-desktop-portal-kde installed and found

- libpipewire 1.2.6 running and working

- Graphic Card used: Intel HD Graphics 5500 (rev 09)

- x86_64 architecture

I tried, with always same result

- deleting the zoom config ~/.zoom

- using wayland or x11 

- use gnome instead of plasma

- update system

- use linux mint from USB and install zoom 6.6.0 (4410) same error

- using QT_QUICK_BACKEND=software

What happend between 6.3.11 (7212) and 6.4.0 (471) that breaks joing a meeting?
