Press M For Map and game crashes to desktop

Is anyone else suffering from this, in Air RB 30% of the time I press M for Map the game CTD. No log files or any files that Gaijin want are created.
Getting I bit crazy with it now as it’s always near to end when I need the map to reach home base and I absently forget about the issue and press M…

Created a case with Gaijin Support but I’m not too sure what’s going on with the support case as I haven’t had a Gaijin update on it for an age.

Here’s the case I opened, took me a while to recognise the correlation between M and the CTD.
