Signal suddenly stopped working on my KDE Linux machine.

[SMGolamAlif]

Using a supported version?

• I have searched searched open and closed issues for duplicates.
• I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

Signal Application is not opening anymore. I am unable to use it on my KDE Linux machine. But I Need signal in my daily work.

Steps to reproduce

It crashed after I attached an Audio file in a chat to send someone. The extension was: ".m4a".
After I attached the file, My crash handler started reporting a crash report. At a time signal App crashed. and I am unable to open it now.

Expected result

The signal App should be on. I have reinstalled it 2 times. but it isn't working.
I Have the latest Virson cause I installed it 5 days before. and I reinstalled 2 times this day.
Uninstall Commands :

sudo apt remove signal-desktop
sudo apt purge signal-desktop

#And I install the app again by following official process :
