High cpu usage after Execute, WorkerThread not close()

[Doaxan]

Clicking on Execute produces high cpu usage until the close the program.
Steps to reproduce:

1. Open CachyOS Kernel Manager
2. Click on Execute (bug, Execute must be disabled) or choose anyone kernel and click Execute
3. Cancel operation or wait for successful completion
4. Check WorkerThread with top -H
   This seems to be caused by m_thread_running is always true in while(m_thread_running) loop.
