Garry's mod stops

I’m loading garry’s mod but the game freezes at the menu. I couldn’t click any buttons nor close the game. Can anyone provide me with tips to unfreeze garry’s mod?

Did you subscribe to anything on the workshop?

I got an entire mod pack with many great mods.

Unsubscribe from them an see if that fixes the issue. You can always resubscribe to them later.
