"Fixed up invalid landscape material instances. Please re-save" error CRASH

I work on my own project in two pcs with Azure DevOps repository. All went good until now. I get this error because i put some holes in the landscape to make a cave. I started getting these when i created and added the Landscape Hole Material.

I don’t know how can i re-save the external actors.
I don’t know if it’s because of those errors but in my high-end pc Unreal Editor crashes almost immediately once i start it, meanwhile in my low-end pc i can stay editing the level for ages. The map check says 0 errors/warnings but it crashes… I need help so i can keep on working remote and collaborative, thanks in advance!
