Engine crash when Physics asset is loaded

papa335678 · May 23, 2025, 9:31pm

Upon opening my physics asset the engine crashes, this happens when it’s loaded into the world or opened in the editor. This started happening after I deleted bodies from the asset and replaced them. Is there any way to retrieve the physics asset, or do I need to start from scratch?

Here’s the log.

Hey @papa335678!

I would suggest just rolling back to an old version of your project, or if you CAN, roll back just that file.

If you can’t, you may be better off cutting your losses, it’s likely you’re not going to be able to continue without doing so.

Let me know how it goes!

I’m absolutely daft, forgot I set up version control. Thank god for Git. Manually replacing the asset through the Windows file browser did the trick, everything’s back to normal now.
