If I recall correctly from recent posts I've read on the Arch Linux forum this is a known bug. The workaround is to use the 5.4 LTS kernel. You may need to use the 2.4 GHz band as well.
Not sure if a fix can be expected anytime soon or not. You could also test the linux-mainline kernel to see if any new additions have improved things. This is a relatively new adapter and it's driver is rather a work in progress. Hopefully it's issues will be corrected soon. Unfortunately, there's very little Garuda can do about Intel's kernel module issues. The driver needs to be improved by the Intel devs.
You could try disabling MAC Address randomization to see if there is any improvement. The Garuda network utility has an easy shortcut for that (or search for instructions).
