Heavily Modded 1.16.5 Version - Failing to launch due to something with "JDK"?

[Phoenix99125]

I'm having issue running a modded 1.16.5 Forge version, I thought I placed everything correctly but it crashed as soon as it started running. It gave me this short bit of code in the Log, anyone know why it's crashing?

BTW I've replaced all the places where it gave my IRL name with (User) for privacy reasons.

1.16.5 is no longer supported on this forum. We only support 1.18.x and 1.19.x.

@HipposgrummWhere do I go to get help then? I've looked everywhere for some sort of help forum and this is the only one I've found.

Try asking curseforge discord or something. They might be able to help you.

I would provide an answer here but I don't think I'm allowed to.
