if you don’t mind setting up a bit, OBS actually also have a replay buffer feature to do that. It’s a good software to have even if you are not streaming because of the virtual camera feature that let you share screen with very deep customization too.
There is also an open-source alternative to this: https://github.com/matanui159/ReplaySorcery
Although it seems to be no longer actively maintained.

I prefer Gpu Screen Recorder as open source alternative
