[1.15.2] crashing issue

[Im_Drowning]

Hey. Sorta new to modding, I'm attempting to mod a server I run off my computer. Mods work solo, but don't work on the server. I was trying to run a vanilla server, I think the issue was that I was not using the forge client. I've gone through and remedied that (I think), now when I try to run the forge server I get the following crash report here. I get this no matter if I have mods in the mod folder or not. The full debug file is here.

 

When running a server normally, not the forge client, I am able to see the items from the mods I've added when I use the /give commands, but they do not appear in my inventory as it is not a recognized item.

 

I've done a fair bit of googling/searching around here and other various forums and I can't seem to find a solution. I did see a different post from a while ago someone asked for the fml, so in case it's needed I'll make that available here.

Will I need to uninstall my previous java?

 

Edit: Downloaded Java 8 version 251, no change. I checked my logs, and everything seems to have the same error.
