I have found the problem. The problem is an asset I bought from the store.

The problem isn’t with an asset that was bought from the store (as mentioned in the previous answer) - it’s definitely an engine problem.

Our characters were working fine in 4.19, but in 4.20 I’m getting frequent editor crashes with the same data, all of which relate to cloth array allocation :

The callstack is long,so I’ve snipped the middle out, but this is where it originates:
