FreeNas 11.3 console output is gibberish

[TurboStore]

Video of the Issue:

I always had this issue and never cared about it because the system worked fine.
I made a mistake in the network configuration and can't access it anymore via the network.
Now I do care about this issue :(

Does anyone have an Idea what could cause this issue?
On Linux and Windows the output works just fine.

Kind regards

I have now reinstalled FreeNAS in BIOS mode.
It was running in UEFI before.

The issue is gone now.
Any way to switch between BIOS and UEFI mode without reinstalling the system?

No, it does require a re-install since the boot devices are setup differently depend on which is used. You can backup/restore your configuration database though and re-install UEFI later, so the downtime is minimal.
