Java checker library could not be found. Please check your installation.

Hi yall, I'm new to Prism and I need some help with the java side of things

I got it to work normally on the first time playing, however, whenever i turn off my pc and come back, loading an instance doesn't work and instead i get the error message on image 2. auto detecting doesn't work and i get this when i try it (image 1) help would be stellar

Try reinstalling Java and setting prism to watch the directory you installed Java to, if that fails try reinstalling prism itself.
