Jellyfin Media Player Crashes on Startup / Blank Screen with NVIDIA GPU (Arch Linux)

[DJZeroAction]

Description:
I am experiencing issues with Jellyfin Media Player (JMP) on Arch Linux using an NVIDIA GPU (RTX 4070). When launching JMP, it either crashes with a segmentation fault or shows a blank screen.
System Information:

OS: Arch Linux (fully updated)
GPU: NVIDIA RTX 4070
Driver: NVIDIA 565.77
Desktop Environment: KDE Plasma
Jellyfin Media Player Version: 1.11.1-2.3

Error Messages / Logs:

Running JMP with gdb produces the following segmentation fault:

Thread 1 "jellyfinmediapl" received signal SIGSEGV, Segmentation fault.
0x00007fffeed044d0 in content::BrowserAccessibilityManager::OnNodeDeleted ()

Steps to Reproduce:

Install Jellyfin Media Player via yay -S jellyfin-media-player
Run jellyfinmediaplayer
The application opens a small command window which closes immediatly.

What I Have Tried:

Resetting JMP configuration:

rm -rf ~/.local/share/jellyfinmediaplayer/

Running with different command-line options (--disable-gpu, --disable-sandbox)
Ensuring Vulkan and NVIDIA drivers are properly installed
Testing MPV separately (MPV works fine)
Running JMP under different desktop environments (same issue)
Reinstalling Jellyfin Media Player

Expected Behavior:

Jellyfin Media Player should launch and allow me to browse my media library.
Actual Behavior:

The application crashes immediately with a segmentation fault
OR it opens a blank screen with no interface

Additional Notes:

This issue seems to be related to QtWebEngine, as the crash occurs in Chromium accessibility code.
Running glxinfo -B confirms that my system is using the NVIDIA driver correctly.
The issue persists across multiple system reboots.
The issue started happening after I tried to open jellyfin-media-player on a secondary nvidia GPU which required another third party driver due to the card being old (gtx285) but all the changes should have been reversed and i cannot exactly tell if that caused it.
 Delfin (video player) works fine and i can access the web client fine and play video.
