We have more reports of failures after several hours with the S3, but we have a few for the S2. However, all the failures reported so far are hard crashes, not the "can't see SSID" error you are seeing. Some of these seem particular to the WiFi configuration and/or equipment at the user's location.
Each time I have a can't see SSID error the only fix that works is remove power.
Ctrl-C, Ctrl- D does not fix it. supervisor.reload does not fix it. microcontroller.reset does not fix it.
This is on a Pico W with an ESP-01 WiFi module also, mounted on a Maker Pi Pico Rev 1.2 chassis. I don't remember if it was the ESP-01 or W that was guilty. It happens maybe once or twice a month. Running 8.0.0 Beta 6. I will track it more closely now. It looks to me like something gets stuck in the WiFi module and only a power reset clears it.

You did not create the bug. You made it evident. I am tracking your topic to get smrt. This should be action to the Forum administrators.
At best, I should not have been notified of your posting if you had deleted it. Else, I should have been taken to the topic and then told your posting had been removed. I was told the entire topic had been deleted, which is not true.
