Describe the bug
I get an error screen that says the GUI I want doesn't exist or is not supported. I cannot exit this screen once I get into it.

To Reproduce
Steps to reproduce the behavior:

1. Go to Inventory Screen (JEI is Enabled).
2. Click on Tips button near the bottom.
3. Click on 2 or 3 of the 6 tips that appear.
4. Try to click Back button.
5. Error screen appears, cannot exit by Back button onscreen, or with Escape key or other keybinds.

Expected behavior
I should be able to exit the menu and continue playing.

There was no crash, but I had to hit Alt+F4 to exit the game.

Screenshots
If applicable, add screenshots to help explain your problem.

Basic Informations (please complete the following information):

• OS: Windows 10
• FancyMenu Version 1.7.0_MC_1.16.2-1.16.5
• Forge Version 36.0.9
• Minecraft Version 1.16.5
• Active Mods: Modpack Skypopolis 4 - Beta 5

I have also reported this to the Modpack author in case this is their issue and not yours.

Hi! Why did you had to exit the game with ALT+F4? You were unable to click the Accept button?

The accept button took me back to the same tips screen, which had a back button, but that only gave me the same error. Attempting to use the escape key also lead me through the same loop. I forgot to take a screenshot of the tips page, but I can go back and find it again if you need me to.

Strange o.O Will try to reproduce this, thank you for telling me! :)

Fixed in FancyMenu v1.7.1! Thank you for your report!
