TS5 bugreport crash (Linux amd64 Ubuntu/popOS 21.04)

Hi TS Team,

the bug report link in the TS5 beta uses an old bug report page, so that my report went to the wrong address at first. Here is my report for the forum:

Teamspeak beta59 TS5 (build 1625645480) crashing on linux while playing csgo and using “mouse5” as push to talk key. Every build i tested yet had this issue.

Terminal message:
