Cannot install KDE again after remove it?

I installed KDE and then I had removed it. But after that I installed it for the second time, it does not work

Any errors shown in journalctl or elsewhere? Which version of Qubes? (4.0, from your other post it seems).

I cannot run qubes now ?
Yes. I am using qubes 4.0.4

This was not really helpful.

Do you get this error while trying to run Qubes?

No. actually I got it after upgrading fedora 32 to 33 and Debian 10 to 11

In case you have backups (and you should!) you can probably restore you system relatively quickly (it’s what I usually do to avoid repairing it). Apart from that, note that Fedora 33 is EOL.
