That's a lot of mods! Does it freeze for about 5 seconds and then it's playable again for a while and then it freezes and so on? If so then the problem is caused by having uninstalled some mod(s) incorrectly, and since you have so many mods (and most likely updated/removed many) it's very possible that this is the reason for the freezes. What happens is that your game tries to load mods that are already uninstalled, causing freezes, however I don't remember the specific details. The main thing is that your save is rather corrupt. This happened to me before and I had to create a new character in order for the freezes to stop. However, I think that if you install and uninstall correctly the specific mod(s) that is/are causing the problem then the freezes would stop. However, finding that specific mod(s) would be quite challenging since you have so many and you don't know which specific version of that mod(s) is/are causing the problem, even if you had already uninstalled it/them. So, unless you're willing to look for the mod(s) that is/are causing the problem (which would take a lot of time), I would recommend starting all over again with a new character and then being cautious when uninstalling mods. But first check if the freezes occur when creating a new game. If they still do then it may be a mod conflict or even still the consequences of uninstalling mods incorrectly. Check if by uninstalling all mods and then removing the Scripts folder (remember to back up) solves the problem, however it may only solve the problem on a new game, but not on your original game. If not then you'll have to uninstall Skyrim thoroughly and then install again. Hopefully this helps!
