Lightroom Classic AI Noise Reduction stopped work

For the past month I recently started using AI Noise reduction for football games which has low light at most stadiums. I was editing my shots this morning and all of a sudden I got this message as seen in the photo attached to this post. The issue has continuted to go on all day. Does anyone know how to fix this problem?
