Does it even work on Ubuntu 24.04?

[Xpleayer]

I have it installed on Ubuntu 24.04.

The app shows up when searched for. but when i click on it nothing happens.

when i run it via terminal i get:

error: process ID list syntax error

Usage:
 ps [options]

 Try 'ps --help <simple|list|output|threads|misc|all>'
  or 'ps --help <s|l|o|t|m|a>'
 for additional help text.

For more details see ps(1).
import-im6.q16: unable to grab mouse `': Resource temporarily unavailable @ error/xwindow.c/XSelectWindow/9234.

Am i doing something wrong?
