And like I said; I have too many addons
That's my opinion, as you directly said.
My context of course.
How much, seriously, are those addons used?
10%? 25? I dare say 30%?
As much as I love the features of ULX, I personally don't see them <all> being used, and could imagine some being pruned.
Part of the reason we've tried to make ULX modular is due to that.
I could imagine having 20-30 addons. (My base Sandbox server back in my day had ~10).
But 190? It seems to me to be asking for the trouble you're having.
Other than a 'remove all - add 5 back at a time - restart - try duplicating' method, or removing all but essential, trying to keep to less than 20 or 30 addons, I really don't imagine a way to determine, other than what you've already stated.
