[jakubsuchybio]

Describe the bug
From the logs:
[2024-12-29 07:43:16:231] [FATAL] [Program] System.NullReferenceException: Object reference not set to an instance of an object.

at System.Threading.ThreadHelper.ThreadStart()

To Reproduce
Don't have a repro, but lately when I run it over night, this just happens...

Expected behavior
nhqm shouldn't crash

Version affected (please complete the following information):

• Version number 0.6.12.0
• STABLE

NVIDIA driver version
566.36

Hardware
NVIDIA 3090
i9 - 9900K

Logs
I don't have a capacity to go through the logs if there are some secrets or not... That fatal log is from those logs

Additional context
Other behavior that is happening is that excavator is restarting, but there are no errors there. I just set "do nothing" when some error in excavator occurs, will monitor further
