Linux keep crashing changing node js didnt help
putting node js compatible or copying it to the nwjs-lnx of the windows version of rpgmaker provided a temp fix but the linux output has glitches and other problem but its playable which is strange it was stable before
the main problem is the font or how node js bundles it even with proper fonts dejavu sands in my linux matching it didnt work but copying the nwjs-lnx ideal version to nwjs-lnx folder of rpg maker mv windows or proton verison worked you might want to experiment with different versions
nwjs 79.0.3945.130 for linux seems ideal
this is a fix for the linux version
default nwjs works fine for windows but you might want to update experiment with the version you think is ok and make backups
