Zbaitu laser bloked

Good day.

Could somone help me with my Zbaitu Laser M81 FF80 Air? I was trying to prime the lens, and now it’s stuck and displays a message that it’s in use or paused. I can’t reset it.
I don’t know what to do anymore. I’ve already disconnected and reconnected the power several times, and it’s still stuck.
Could it be that the motherboard is broken, and can I order it separately somewhere?
Sincerely,
Bjorn

It’s possible that you need to also unplug the USB cable to fully reset the controller.

You can also reset the current device connection by right-clicking the “Devices” button in the Laser window here:
