On a certain project Reaper keeps crashing randomly, often already when opening, sometimes while navigating, sometimes while rendering, sometimes when closing.. this way I am even struggling to migrate the project to a new one as whatever I do, chances are not small that Reaper crashes.
Worst is that I have no idea what is causing the crash and as this is one of my first slightly bigger projects in Reaper I am afraid that I might face a lot of crashes during my Reaper journey..
Anyway, here is one of the crashlogs, when Reaper crashed on Startup - sadly it is not easy to produce other ones as most of the times pressing Report.. does not open any window (though I remember to have read in one of the first ones which occured during navigation something about Fabfilter Pro-L VST3 in the first 3 lines..but in this one for example no plugin is mentioned:
