I am using visual studios with jdk 17 and libgdx implementation. I ran into this issue awhile ago and it is pretty annoying as I can run my code fine with no issues, I just cannot use autofill or see errors underlined. I am using github to work on this across devices, and I did not originally have this issue when I first built my script. After a few commits, one device does not have this issue but 2 do. I am using libgdx for desktop development aswell.
