TS3 Client does not start - Segmentation Error

Hi Guys, please can I have some help.

I am running Fedora KDE 43, fully up to date.

I have installed via the flatpak and via the .run file from TS official site, I am experiencing the same error for both installations.

Error:


QCoreApplication::applicationDirPath: Please instantiate the QApplication object first
qt.qpa.plugin: Could not load the Qt platform plugin "wayland" in "" even though it was found.

I have been round the houses for several hours, and I am sure this is something that I have done to my system, but I have no idea how to diagnose this? I have an oldish cpu (AMD Ryzen 7 1800X) and I found some random post that said teamspeak does not always support older CPU’s, how do I find out if this is my issue?

I have also done a gdb thingy, but this did not shed light to my, new to linux, brain.

I don’t know where or what to do next, is this a bug with TS3?

Thanks for any help :smiley:

I’m having a very similar problem. I believe its due to QT5 not being available anymore, and using QT6. I havent found a working solution yet, but if I do I will post. I doubt it, but hopefully they update it.
