Problem with Point Lights in EEVEE - Decreasing the Shadow Cube Size fixes them temporarily

Whenever I’m increasing the Shadow Cube size, The point lights just… Stop working, except of the Sun lights. Also, whenever I’m doing that, Blender severally slows down, though I disabled Ambient Occlusion, Screen Space Reflections and al that. It only occurs on EEVEE engine. The Point lights on Cycles however, work just fine, no matter how much I’d increase the Shadow Cube Size. This keeps happening to me since yesterday, on every other blend. project, and I think, it haven’t happened before.
