Segmentation fault unity when trying to open Unity to do an import (unityci/editor:ubuntu-2021.3.0f1-webgl-1.0.1)

Bug description

I have a docker image building and activating. When I try to run the command to open unity in order to import the project it will hit a Segmentation fault

How to reproduce

Use this Dockerfile in a Unity project of the same version:

FROM unityci/editor:ubuntu-2021.3.0f1-webgl-1.0.1

#Copy repository into image
COPY . /opt/repo

ARG UNITY_SERIAL
ARG UNITY_USR_NAME
ARG UNITY_PASS

#Auth with unity
RUN /opt/unity/Editor/./Unity \
-quit \
-batchmode \
-logfile \
-nographics \
-serial $UNITY_SERIAL \
-username $UNITY_USR_NAME \
-password $UNITY_PASS

#Open Unity once so it can do an import
RUN opt/unity/Editor/./Unity \
-quit \
-batchmode \
-logfile \
-nographics \
-buildTarget WebGL \
-projectPath /opt/repo

-

Expected behavior Unity is able to import the project and close successfully

Additional details I am fairly sure the

I have tried a lot of different things. This used to work on a previous version of Unity (2020 something). I thought it might have been that I am using an M1 chip Mac but I reproduced it on a windows machine.

I have resolved this issue, a git clean of the repository got me past it but there is a new error where unity cannot find mono, going to dig into that and produce a new ticket if I can't work it out.
