URP Forward Renderer with stencil

When I check the ‘stencil’ box in my Render Object within my forward renderer, the stencil buffer doesn’t seem to do anything, and when I click another asset and then go back to the forward renderer again, the stencil box is unchecked and all my stencil settings are gone???

I tried updating to the newest beta version of Unity, since I’d rather not downgrade, but that didn’t help.

How can I check the stencil option?

TL;DR: Unity doesn’t let me check the stencil option in Render Object. How do I fix this??

Same issue. Pls help
