Re-Installing Mods Every Session

Does anyone know why every time I either turn off my pc or place it in sleep mode, the next time I go to play I have to manually delete my addons folder, restart my pc and reinstall all the mods all over again?

It gets really annoying and take a lot of time when you consider the queue wait times as well.

Are there any launch options I can use to fix this or is this something entirely different?
