We are noticing on several Ubuntu 22.04 machines that the latest release (https://github.com/pupil-labs/pupil/releases) of pupil_capture crashes immediately on startup. We can run from master/dev source, though the CPU use is crazy and it is causing us issues as we are using two pupil core headset simultaneously and running on two separate workstations but even so > %75 of all cores CPU cycles on both workstations (Core i7 8C/16HT, 32GB RAM) are being used on each machine.

------------------------------------------------------------------------
cysignals failed to execute cysignals-CSI: No such file or directory

Unhandled SIGSEGV: A segmentation fault occurred.
This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Python will now terminate.
