5GHz radio intermittently disconnects on Comfast CF-EW72 V2

I have a Comfast CF-EW72 V2 router
The initial firmware was successful.
On 23.05.2 updated successfully, but the SSID of the 5GHz radio periodically goes into the off state.
After a reboot everything seems to be ok, but after the next reboot it turns off again.
Rebooting with an error takes a very long time: 4-5 minutes

strange, but on page device lists MT7603BE chips for 2.4GHz 802.11bgn, MT7663BEN for 5GHz 802.11ac
I have MT7603BE and MT7613BE in the photo...
Maybe this error is related to this?
