Can't lauch Minecraft 1.15.2 with Forge!

[Rafaaba]

I've been using forge 1.14.4 for a while and decided to install 1.15.2 so I could play in the most recent version, but it doesn't work for some reason, and now 1.14.4 doesn't work anymore. Can someone help me with this?

[Ugdhar]

Post you debug.log please, it should give details on what is going on

[Rafaaba]

Is this the debug?

I don't think so, debug.log from my experience always starts like this:

Looks like you have optifine for 1.14 in there.

Make sure if you go looking for a 1.15 version that you read the changelog, it will tell you what version of forge to use, IF it is compatible with forge.

[Rafaaba]

It is working now
Thanks!
