Getting games new version back

I’m not sure if this is the right topic, but here is my problem:

I was creating a union and it was to big, and I had to close studio on task manager
and the games new version is now reverted back to the old version.

I have no idea what this is, and I would like help as I spent HOURS making this new version.

Have you tried checking auto saves? That usually saves me a bunch of time whenever studio crashes after a playtest
