My MEDIATEK Corp. MT7922 802.11ax network card is dropping connection after moving from 6.2.0-21 to 6.3.0-7 official ubuntu kernel version. After selecting old kernel, everything works, but after selecting 6.3.0-7 my plymounth screen for disk decryption is showing in top left corner instead of the center and after booting up my wireless card is working for some period of time and then suddenly stops for 5s and then works again.
Except for ping stats in console, no information is shown in dmesg or /var/log/syslog.
My laptop is Lenovo Thinkpad L14

As you can see, no information about dropping connection is shown.
I tried to disable power saving using iw dev wlp6s0 set power_save off but it didn't helped.
If this is necessary, I can bisect the kernel version to get to the root of the problem, but I would require a little assistance in doing so.
Additionally, I've seen that on reddit users found some kind software issue with roaming in card one version down, but I am not sure how to disable roaming using iw.
