ok i solved this problem: what happens is that the RGB software uses your IP address to connect your PC settings to your phone. so i guessed thats how they were saving my fan settings data even after i was reinstalling the software.
to fix this i completely deleted everything to do with the TT RGB software and redownloaded. do NOT install it yet, go into settings and turn of all ur internet connections and take out cables (go airplane mode). then once offline install the software and it will promp you saying that it has no internet connection, just continue and extract all the files.
this worked first time and the software didnt crash after 1 second and is still working right now :). will keep u updated.
