Hi there,
So what code are you using, Sounds like it’s writing something where it shouldn’t?
Do you have Arduino BLE installed on the system? Remove it and Compile again.

I run same code on wokwi and it gives same error there too then with chat gpt code it created xtask freertos with large memory then it works

Hi there,
Try removing the Arduino BLE from the IDE.
I know it’s crazy :crazy_face:but just having it installed causes some weird issue with the ESP wifi & BLE stuff.
I beat my head against the wall for a 3-4 hours one night and I was trying different BSP’s and rolling things way back , Code that worked would’nt anymore. Turned out I unistalled everything but what I was using for the ESP32c6 or s3 but once I removed Arduino BLE everything worked again. Even though the code would compile , just made the thing Boot loop until in boot mode and a reload was done with out Arduino BLE installed at all.
YMMV.

I think it was a WIFI & BLE code compile, nothing fancy just scanners both Wifi and BLE and print Availables in both Networks.
