Accidentally deleted nodes in compositing tab. Can't recover it? I accidentally deleted the 'Render Layer' and 'Composite' Node. I panicked and didn't know what to do, so I thought maybe if I close my file, itll come back when i open it again. So I closed my file, and obviously saved it because it had all my progress, but my dumb self didn't think through that it might save the action of deleted nodes as well.
I have tried everything to reverse this but nothing works. I tried manually adding these nodes. I do get the composite node fine, but the 'Render Layer' has missing bits.
I even uninstalled and re-installed Blender to fix this, but nothing.
I have attached images with the original 'Render Layer' node and the one I'm getting now (which doesn't have all the properties that I need).

TLDR;
Accidentally deleted 'Render Layer' and 'Composite' Nodes. Can't recover them no matter what I do. Manually added nodes have missing properties.
Do not worry, this looks easy to fix, even if this diagnosis is wrong.
The image looks like render passes that were previously enabled have been turned off, and thus aren't showing up in the render layer node. Check this manual page for information on render passes. https://docs.blender.org/manual/en/dev/render/layers/passes.html
