Do you mind providing the file of said player? (The file is named in UUID format, under data-storage/Slimefun/Players/<uuid>.yml)

I renamed it to .txt, because github does not support uploading .yml
slimefun-player-data-file.txt

This aint a fun issue to solve sadly.
The quickest and dirtiest way is to delete the file or shorten it.

Hey, so I don't believe the extremely hefty file is the cause of your OOM. The string at most will occupy 21MB, which implies that your server is already nearing the max heap limit.
I'd suggest you check via a heapdump on OOM (-XX:+HeapDumpOnOutOfMemoryError).
