Well, I found a solution to this problem that does not require disassembling the equipment, I hope it is universal. After disconnecting the key, I went to the recently cooked menu. I clicked on the name of one of the recipes. Then the device displayed the command to connect the key. After connecting the dongle, everything works fine: the network search was successful. Then, when I click on the sync symbol, it takes a little longer than normal, but successfully. The newly added recipe and others open correctly.
