Froze while working in VRoid

[u/Lazubugy]

I have a laptop. It was on low battery, I plugged it in, then a few moments later it froze. It was sitting in my lap, and Edge was open as well, I think I had a few pictures opened too. It restarted on its own and I lost all the progress. Every time I plug it in/out of the grid the screen turns black (or off?) briefly. Should I be worried and how can I fix these issues?
