Ok, I have this bug everytime I play this game, I found some fix, I'm gonna try to explain it clearly
First U need to download the new Nw.js here ->
You must be registered to see the links
, ddl the Normal version, it's gonna download the last MAJ of the core files of the rpgm maker games.
After that c/c all the files in ur game folder, overwrite everything, then delete the Game.exe and rename the nw.exe -> Game.exe
If have the error 'name' when launch the game after that, open Package.json (in ur game folder same folder where game.exe is) with a Text editor and Add Game in this line :
"name": "", change it to --------> "name": "Game", save and try to start the game again.
Optional : if u still have infinite loading, create a shortcut of the game.exe (Right click on it create shortcut) -> Right click on the shortcut -> Properties and then in the properties window go in the Shortcut tab -> In the "Target line" add after xxxxxx\Game.exe" this command - PROTON_USE_WINED3D=1 to make in look like that
xxxxxx\Game.exe" -PROTON_USE_WINED3D=1 (The space between Game.exe" and the command is important).
Hope it fix it for u as well
