This sounds like a bandwidth management issue, which I know Linux
doesn't do as well as Windows (on Intel graphics either).
Firstly you seem to have the wrong (old) kernel still installed. It
should be version 5.19 so please try fixing that with:
sudo apt install linux-generic
or
sudo apt install linux-generic-hwe-22.04
and reboot.
If the problem persists after that then please run:
journalctl -b0 > journal.txt
lspci -k > lspci.txt
and attach the resulting text files here.
