Change collision Fildelity = server is crashed

So as the title has mentioned, the studio simply crash when i change the CollisionFidelity property into a different types. I tried to look for solution in the forum and online but it has no result, anyone knows how to solve, i would be really appreciated.

Have you tried restarting/redownloading studio?

I have tried restarted multiple times yesterday and it didn’t work. However, when i changed it just this afternoon, it doesn’t crash anymore
