Can't tell if it's me, but me and my friend crash when enabling render mode in the latest pre-release of mine-imator.
steps to recreate:
1. load a project (literally any)
2. turn on render mode (make sure to use combined render pass)
if that doesn't work i guess here is the project file: https://www.mediafire.com/file/hjpg7gmcug3ut56/hallway.rar/file
