Roblox place upload messed up

Yesterday, i checked my main game, it was/is working.

And my test place broke, so i decided to copy the working main game, over to the test place.

But once i have uploaded it, i tried to click play game.
And it starts the server normally, but then it freezes on instances.
And never loades, what is the problem?
A working version doesn’t even load?
Happends to all places i update now.
Even if i revert to an old version.

[I fund out that my module was over loaded, trying to compromize it, but it’s still having loading issue without my module.]
