Frameworks Version: 5.68.0
Operating System: Linux 5.11.0-40-generic x86_64
Windowing system: X11

-- Information about the crash:
(English is not my first language,please forgive my spelling mistakes.)
- What I was doing when the application crashed:
opened net-ease-cloud-music Q2vray then change user
- Unusual behavior I noticed:
when click change user buttom,HUD teared apart
- Custom settings of the application:
correctly configued default Q2vray + cgproxy default

The crash can be reproduced every time.
