Mongo db wont start in Splunk in WSL2 env

I have successfully installed Splunk in windows WSL2 (ubuntu 22:04) several times - but having now installed a newer version of splunk on initial install mondo crashes straight away - can anyone help with the following mongo.log output please?

the main error seems to be:
