MacBook black screen randomly resuscitated what now?

After 4 years of great use I dropped my 13” MacBook Pro M1, while open. It kept working that day, I put it to sleep, and in the morning when I opened it again the screen was black. I tried everything, the Mac was working with an external monitor, but the screen was still black. After a few days charging it and using it on the external monitor, I opened it again and the screen was working again. The corner where it bumped now has a light leak. What should I expect now?. Will it keep working or will it randomly die again on me? Can I do something to keep it working? Pictures of the bump and the light leak.
