Well it's a marked improvement. Doesn't crash anymore, but now when in game I only have a blank map with the player icon being the only thing that shows up.
Which now happens in blank projects too :(
I cannot reproduce it, neither MV nor MZ, nor local nor web browser deployment. I wonder if it is an OS problem, as I only have Windows devices at home.
The last thing that comes to my mind is that when starting your game, you can press F12 to open the debug console, go to the "Console" tab, and check for error messages there.
When you feel comfortable, you can send me your project via mail@aerosys.blog
