Not letting me import a model or animation

When I press the import java animation button. It does not open my files, but works if I drag the file in. But when I try importing an animation. It does not open my files, but if I try dragging the file, it says it does not support the generator. But it should support it because before I updated to 2026.1, I could import animations and they would support it. And those models still work in 2026.1.
