Cloth Simulation Seems To Have Broken (Upgrade From 5.0.3 to 5.3.2)

I’ve tested this issue and it seems like it has nothing to do with materials but cloth simulation. It was working just fine in 5.0.3 and previous versions (project started in 4.25) but I’ve upgraded the project to 5.3.2 and it seems to be somewhat broken, even though the affected area doesn’t even have any simulation going (it’s only the long parts of the scarf).

Any ideas on how to solve this?

5.0 version:

5.3 version:
