BLE HID device stopped working with MicroPython version 1.20 and up

[Heerkog]

I have written a library with several HID services. The library, however, stopped functioning with MicroPython version 1.20 and up, and I have no idea why. The client just seems to disconnect shortly after it has connected. Neither the MicroPython documentation, nor the BLE examples seem to indicate significant changes that would cause such behavior. Any help would be appreciated in tracking down the issue.

The library can be found at:
