Well, it was worth checking. Thanks for the suggestion. I guess I'll file a bug report.
Something might change outside your machine: you installed another router, more devices have been added to your wifi network, including ones actively using multicast (IPTV), some of your neighbors installed new access point working with higher power on the same channel...
I have seen various recipes, but I have not tried them, so unsure concerning real effect: explicitly disable 802.11a and 802.11b low bitrate modes, try fixed frequency instead of autoselect, disable dual frequency channel mode on 2.4GHz band.
My couple of data points for the same Intel AX200 device: (almost) no issues for 5GHz and fixed frequency channel, some days I had to "kick" the adapter often enough to restore connection to a 2.4GHz access point with automatic frequency selection and enabled 40MHz mode (2 frequency channels).
I assume, you have tried backports kernel and latest firmware.
