15b4 Relentless Fusion Paint and Tracker Problems

For 45 mins yesterday and 30 mins today Ive been trying to simply paint out a small defect in the frame and track the paint job to the shot. When using the tracker Resolve often hangs perpetually to the point I have to force quit after about 2+ minutes. When loading the fusion page back up my paint strokes are gone. The Inspector says "no object selectable" and when I try to use the select to to re-select the paint strokes in the viewer, nothing is selected. So the paint job I did is completely gone and I have to start all over again. What should be a 2 minute job has become literally impossible, because the tracker hangs or I lose my paint job or both. I finally had to give up and move on to other things because the job wasnt getting done and I was losing lots of time. Below is a link to the diagnostic logs.
