Bootcamp on startup is on lowest brightness and cannot change. (MBP)

It all started this morning, since I listen to podcasts on youtube before bed and barely use my mac side but still update it I use my bootcamp partition for most of my stuff.

so I went to bed with the screen dimmed all the way down and then went to sleep then when I woke up my computer was shutdown but still perfectly fine I then started up windows and then after the starting windows windows logo screen the screen goes black since it is dimmed all the way down and now I cant brighten it back up.

Please help I need this bootcamp partition.
