[THN1]

Hi,

in LinuxMint 22.1 Cinnamon, I'm getting traps

traps: Thread (pooled)[4692] general protection fault ip:7c037b846024 sp:7c0365fffc60 error:0 in libQt5Widgets.so.5.15.13[7c037b54e000+3f7000]

and segfaults

in libQt5Widgets when using the System Cleaner in stacer 1.1.0. After such crash, I no longer have a keyboard in various applications.

Any idea?

Thanks!
