Problem with RT-AX58U after 3.0.0.4.388 upgrade

[bmn1]

After upgrade to 3.0.0.4.388 on my RT-AX58U I got serious problem with the web UI when I activate WireGuard. I've tried both Factory Reset and Firmware Restoration, but the same problem appears when I enable WireGuard. I've even tried installing Merlin, but then WireGuard doesn't work. Anyone else encountered this problem and found a solution?

After flashing the firmware you want, did you do a full reset to factory defaults?

What's the problem?

Extremely long response times, but it's a bit intermittent.

After fw upgrade to 3.0.0.4.388_22525, the problem is gone.
