WIERD FREEZING when Interactive render

I have an issue I can’t replicate. it happens now and then. this time I was adjusting a plane. and the interactive render was going, and from nowhere the interactive render continues and I can see it progressing, but I can’t touch or do anything. only solution is to end task in task manager. someones else having this same problem?

Is the interactive continuing normally or is it stuck in the geometry phase (Stats tab of the VFB) ?
