Found the solution. For anyone else having this problem, I had both installed the JDK 20 and 17 version, I had to remove JDK 20 which seemed to have fixed the problem. Hope this helps.

Some friends and I have decided to play some modded Minecraft, and since I have a Macbook Pro lying around, I decided to host the server since I didn't want to host it on my Windows pc. I have no trouble booting up the forge server without mods, but as soon as I add mods the server won't start. I have tried with other version such as 1.19.4 and 1.18.2 The mods should be compatible with the version, example of one mod, Create 1.19.2 v0.5.1b. Here is the log.
