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
