Players becoming invisible

yes I know this is a common bug that is being worked on but I decided to provide some more lines of code

i don’t know if this is related to the invisible player bug but this is what I found in the dev console when everybody was invisible in the mushroom forest

Don’t worry, it is. “playerRender”

how do u open the dev console cuz i tried f9 and i couldn’t get it to work
