hi, I'm on linux I've extracted all the rlcraft 2.9.1c files and then ran 

java -jar forge-1.19.2-43.2.0-installer.jar --installServer ../server/

It has installed successfully:

The server installed successfully
You can delete this installer file now if you wish

and then tried to run it with run.sh file:

Looks like an issue with bountiful mod. Check you have the latest version then contact the mod author.

 

Off-topic. You should use java 17. That is the long term support version. You won't get anything but security fixes for java 18 now java 19 is released.
