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

I have started useing Twine to make a text based adventure game. It begins with your charectr Anthony Recardo, wakeing up in a deep, hole, and he discovers its some kind of underground dungeon, he slowly discovers its more than that as he finds secerts

Started the game with random encounters, but decided that having enemies chase you to initiate battle is so much better. #KingdomOfJappoka #Rpg

Been working on some books to add into the game, some lore bits you will be able to find while exploring. #KingdomOfJappoka #RPG #RPGMaker

Been hard at work! Continued progress on the main quest, side quests and some balancing changes!

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

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

A place

Made the starting area for a game i am working on
