Router: TP-Link Archer C7 v.2

Please help!
It's now annoying to get this error. There were no change in channel and bandwidth but my router disconnected and get this message!! I'ts persists since Barrier Breakers and is still not patched until now! I get unstable internet connection.

The AP is cisco 802.11ac 80 Mhz is always in the same channel and same bandwidth and the same country code DE (in beacon). Nothing change! but my router always got disconnected from AP. I tried to set combination of fix channel or auto channel with 80 Mhz or 20 Mhz bandwidth setting in router but no luck. It lost the connection to AP randomly with this message:
