Core2 crashes on ble init

[ZeroChaos-]

I added a bunch of extra printf's so I could find the line which caused the error. On Core2 when I pick Wall of Flipper, or Skimmer detector, or likely anything which uses bluetooth, it crashes as follows

:arrows_counterclockwise: Resetting WiFi, Bluetooth, ESP-NOW...

Skimmer detector fails on BLEDevice::init("");
While WOF fails on BLEDevice::init("azertyuiop"); during initializeBLEIfNeeded()

I haven't figured it out exactly yet, but I have likely confirmed the cause.

I added some code to ensure the wifi was not initialized when switching to bluetooth

  esp_wifi_disconnect();
  esp_wifi_stop();
  delay(2000); // Yes that says 2,000
  esp_wifi_deinit();

When this runs I get this output

E (105781) wifi_init: Failed to deinit Wi-Fi driver (0x3001)

Predictably, when it tries to init bledevice it fails because wifi is stuck. I'm not sure why wifi can't deinit, but I have to believe that's what causes bluetooth to fail to init.
