When a player rejoins the same server multiple times, all scripts get frozen

[Jblocks12321 (physic)]

I’d recommend using something like ProfileService or DataStore2:
ProfileService: ProfileService Tutorial!
DataStore2: How to use DataStore2 - Data Store caching and data loss prevention

of course this is a personal choice, but its recommended if you dont know datastores too well

Edit:
are all those scripts in the screenshot datastore scripts?
