Ender 3 V2 neo printer halted. kill() called

What is the problem?

When I start printing anything, it completes the autoleveling and then this error appears, and freezes the printer, manual controls don't work.

What did you already try to solve it?

Adjusting eccentric nuts (I think the problem is that the Z axis is not aligned).

Have you tried running in safe mode?

Yes

Did running in safe mode solve the problem?

No

Check your bed, and if you have a sheet, check beneath that.

In addition, you have an undervoltage issue

Thanks @Ewald_Ikemann, Wdym with checking my bed? it's working properly? Or leveling it? I'm kinda new to all this so don't really know what to look after.

We appreciate to write full words. This is an international site and not all readers understand cryptic abbreviations.

If there are obstacles.

Due to the homing: Do you use sensorless homing?

'Homing failed' implies there was an issue with the probe or limit switches that were supposed to have triggered. I would probably guess it's a hardware issue, perhaps a loose connection or something.

No, I use the stock switches, but sometimes it bugs out and the stepper starts clicking loudly. I don't know why, I checked all connections, only thing I didn't look at is the motherboard. Thanks for explaining though. By the way, solved the undervoltage issue.

Could it be a loose connection from the motherboard? Because I checked all stepper and switches' cables.
