Rigidbody and forces not working after unity crashed

Iam creating tiles using a script and i made 20000 instead of 2000 tiles, which caused unity to crash - but now when i run the game, my ball wont move unless i move it with transform.localposition instead of rigidbody add force which worked right until Unity crashed.

what should i do?

For some reason, if i copy everything to a new project, it works.
anyone knows a better solution? i really would hate to create a new project every time unity crashes…
