Modpack Problem

[Poseidon]

Hello,

So I'm having this problem which doesn't let me interact with buttons on the multiplayer/singleplayer tab when you launch a modpack.
I can't select multiplayer servers or can't create singleplayer worlds because I simply can't press any button.
Reinstalling technic and reinstalling the modpack didn't fix the issue. Is there a way I can fix it?

I appriciate all the help.

Thanks in advance
