Not sure if this applies to all ESP32-S3s since I only have the ESP32-S3-WROOM-1-N16R8 to work with and I've already lost so much time to this puzzle... I'm glad I found your Github because it seems the only good ESP32-S3 page around!
I'm working on porting ESP32Radio-V2 to run on the ESP32-S3 and I discovered something interesting... if GPIOs 33 and 34 are allowed to be probed during this loop (already excluded 0, 22-32, 35, 36, 37, 43, 44, 46):
for ( i = 0 ; (pinnr = progpin[i].gpio) >= 0 ; i++ ) // Check programmable input pins
{
pinMode ( pinnr, INPUT_PULLUP ) ; // Input for control button
vTaskDelay ( 10 / portTICK_PERIOD_MS ) ;
if ( ( progpin[i].cur = digitalRead ( pinnr ) ) == HIGH )
{
p = "HIGH" ;
}
else
{
p = "LOW, probably no PULL-UP" ; // No Pull-up
}
ESP_LOGI ( TAG, "GPIO%d is %s", pinnr, p ) ;
}
vTaskDelay ( 10 / portTICK_PERIOD_MS ) ;
At this stage:
WiFi.disconnect() ; // After restart router could still
vTaskDelay ( 500 / portTICK_PERIOD_MS ) ; // keep old connection
WiFi.mode ( WIFI_STA ) ; // This ESP is a station
I get a crash:

I didn't even think to disable them (like I did with other pins as listed above) because I thought they might be exposed on other S3 boards. But now that I triple-checked your table, I can see there's just no documentation on them. So, whatever GPIOs 33 & 34 do , they can't be allowed to be set as input. They cause a crash on WiFi.mode ( WIFI_STA ) ;.
Sidenote that 22-25 probe fine but they do display "Invalid Pin" as an error message. Probably 35-37 also probe fine but I haven't tested.
