Flashlight won't turn on

Hey guys. Hope this post finds y'all well. I have alil problem that has been bugging me since the last April sec patch. Yes, since last month. I didn't make a fuss abt it eventho twas kinda inconvenience to not be able to use one of the most important features of all - the torch/flashlight. I thought the May sec patch would solve it but nope. I just installed the May update moments ago and coincidentally just now, we had a power interruption but as u can see on the attached photo, flashlight wasn't working. Idk which app is using it bc i didn't have any current running app(s) on the bg and have optimized as well .. I checked settings and all the best I could but couldn't figure out how to fix this. Any insights would be greatly appreciated. Thank u.
