It happens for you consistently?

[oppressor1761]

It does not influence any functionality. It happens every time my hotspot automatically closes without connected devices.

Also confirm exactly same issue on same device

[mhonis]

This crash happens to me pretty frequently on Pixel 8 even when devices are connected to the hotspot.

A workaround for this upstream bug has been implemented for the next OS release.
