Scene does not work, no error, no crash?

Today I wanted to work on my Scene, but as I started it, it just stoped working(no error no freeze), it just stopped continue with the code…
I can’t walk, my inventory isn’t loaded, …
I tried to reimport all assets but it didn’t help.
Is there any other way to fix a “broken Scene”?

What’s the global timescale set to?

Answer: Timescale was set to 0
