Looks to be related to this change: 4382eb0
Looks like TURNING_OFF can be triggered when not expected. A simple null check should suffice.

Is it possible that you can release a quick fix Version for this?

[randdusing]

PRs are always welcome, but I may be able to raise one myself this week

[EinfachHans]

Just create the PR. That was not possible for my Java knowledge😃

[randdusing]

I've released 4.15.14, so this should be fixed now.

I was able to force the Crash by toggling Airplane Mode. This doesn't crashed now to think it works. Thanks 😊
