ok looks like it needs more connections, which could be causing issues.
I suggest not flying the drone manually. you need to make sure you a move a decent distance between photos
if you can fly a double grid, with camera at 45 degrees. (straight down won’t stitch well)
otherwise multiple overlapping obits or both.
also for walking around do it 3 times moving closer or further away.
I would potentially even walk around the laserscan locations a few times each. just so you have some photos close the scans that can then link back to other photos.
if you can’t get back on site. then using control points might help.
