Docker - Couldn't create the mpm-accept mutex - docker

Question

My Docker container keeps restarting with the following error:
Operation not supported: AH00023: Couldn't create the mpm-accept mutex
(95)Operation not supported: could not create accept mutex
And I tried some of the solutions online including platform: linux/amd64 switching docker restart etc...
THIS solution does not work for me.
However I did not manage to edit httpd.conf file, the solution offered HERE because I cannot access docker image to do that as it keeps restarting.
Does anyone now how to surpass this error? I am on Mac M1.

Thanks to #Bets, the problem was solved with adding the following into Dockerfile:
RUN echo "Mutex posixsem" >> /etc/apache2/apache2.conf
