Better MC 4 server pack is giving me "Error: Could not find or load main class @user_jvm_args.txt" when i try to run it.

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

Open this file and remove the #

at # -Xmx4G

the 'user_jvm_args.txt' file resets every time i run the 'start.ps1' so changing it doesn't make a difference

Remove @user_jvm_args.txt from your script and replace it with -Xmx4G
