[Mne_analysis] mne.gui.coregistration - coloured fiducial dots not showing

Dear mne community,

Sorry again for another error message. I'm trying to run mne.gui.coregistration, but while the MRI appears to load (there is a head) there are no fiducials plotted. There is a fiducial file that is found in the watershed folder for my subject, but I cannot see any of the fiducials plotted so cannot edit them if needs be.

I'm running mne python via spyder on linux, but not through anaconda, because anaconda clashed with something in my VM and so previously the GUI wouldn't even launch. My sys info is below. One thing to note: I don't have pyvistaqt because when trying to install it there is an error with pyqt5 version 5.15 and that dependency cannot be loaded, so pyvistaqt also failed to install.

Do you know why the fiducial points are not visible in the GUI?
As an aside, the linux system I am using is the one bundled with freesurfer as a VM for running freesurfer on windows. A bit off topic but do I need a different linux distribution to make this work?

Any help would be really appreciated.
