Bluetooth classic SPP mode crashes (ESP-IDF) during pairing

[X-Files]

Hi,
I'm currently trying the 'bt_spp_acceptor' example code (ESP-IDF) on a TTGO device.
When I use my Android cellphone (Motorola g7) to pair with it the device crashes and it keeps rebooting when I cancel the pairing (by clicking on Cancel) during the Bluetooth pairing code confirmation request, or if I wait too long before clicking on 'Pair'.
However, the device works fine if I allow it to pair (by clicking on Pair) quickly. This happens all the time and not just randomly.

- When it crashes it produces the following log:

Guru Meditation Error: Core 0 panic'ed (InstructionFetchError). Exception was unhandled.

I used the latest ESP-IDF library code - Could you, please verify?
Thanks you.
