Does anyone know why this is happening and how i can fix it?

Village of Jappoka. What does everyone think?

Made a little village

One of the Areas that have been remade in Uvery V. 1.2.1

New art is still in the works, slow and steady, and I have been working on remaking the first few areas.

Anyone know how i can fix this? The only solution i found, copy/paste package.json from a new game into the one im working on, didnt work

Any idea why this is happening? The green triangle(player) shouldnt be disappearing. Trying to make something like Asteroids

Made the starting area for a game i am working on

A place

Booted up RPG Maker Mv and got this error, how can i fix this? Its only for one project, my other ones work fine
