SUMMARY

After login the OS Will stop responding to mouse and keyboard, mouse movement is seen but not responded, the keyboard is active only in the last active window, but you can switch through alt+tab.
logging out and logging in via alt+ctrl+del solves the problem of freezing (seemingly in KDE until the next reboot) in MATE, after a while, it can freeze again. 

I tried, add

   KillUserProcesses = yes
# in /etc/systemd/logind.conf 
but bag go on.

So you have both Plasma and MATE installed?

If so, I strongly suspect that this is caused by conflicting packages and would recommend that you contact some Arch people for help.

no, all systems were installed in parallel

What do you mean "in parallel"? On different computers?

one notebook - 4 different OS
Comment 5 Nate Graham 2021-04-15 19:37:41 UTC 
So each one on a different partition?

yep
Comment 7 Nate Graham 2021-04-19 16:15:35 UTC 
Ok.

Still no idea what this could be. :/

This bug was reported against an outdated version of KWin. We have made many changes since the. 
If the issue persists in newer versions can you reopen the bug report updating the version number.
