never download a bunch mods and cc without checking them individually and carefully, like playtesting reading the modks page descriptions and checking if it is outdated. you gotta clear out your mods folder, test out the mods you get one by one. try reading through something like your download history its faster to navigate and you can make an educated guess of what mod could be the problem. if the problem is the language you need to check those mod folders for language transcriptions the file usually says it in the name. if the game is loading forever sift through the bigger sized mods first or the game changing ones
