Reaper crashes when trying to render

Hello reaper family! Reaper is crashing everytime I try to render a project. I have tried freezing effects and and changing the bit rate of the pcm wav but still crashes. It has been fine with previous versions. Thank you in advance! Paul

Crashing how? Immediately as you click Render? During rendering after some time? Always at the same place for the same project? For all projects or just a specific project? Rendering to what? mp3? wav? flac? etc...

Crashing pretty much as soon as I press render. I was mixing down to 16bit wav. I eas able to get the session to render by freezing every track instead of just some of them though. Take care and thanks!
