Created attachment 57569 [details] Console output from Wine 2.3
Perhaps this bug needs to be reopened, as I am experiencing similar symptoms with Wine 2.3.
That would be a different bug and require a separate bug report.
err:winediag:FILE_CreateFile Too many open files, ulimit -n probably needs to be increased
Have you tried to raise the limit?
