Unhandled Promise rejection makes all my game's data stores nil

i always get that one error Unhandled Promise rejection. at first before making data stores it was alright, but when i made data stores, sometimes that error pops up and my data stores are gone , they’re all nil and stop working for some reason, the lines in my data store script (pcall) do not show any problems at all and dosent print the warn it just does not load any data with no problem
