I really don't know enough about computers to understand how to fix this issue, and i can't find anything that works online.
I'm using windows 10 and running my server off my pc, i also downloaded the server pack (specifically BMC4 FORGE 1.20.1 Server Pack v26) on the curseforge website.
my pc specs are:
rtx 4070
i5 13500
32gb of 3200mhz ram
