The warning you got is a general purpose warning that means there was a big issue with your imagery and no result was possible. It could be an error. It could be an issue with the tags. There are lots of things that can cause no result to occur.
How did you collect the data? It doesn't appear to have been done with Map Pilot Pro so we can't really check what went on there.
It looks like you used an M3T which could have something to do with it.
If it is anything like the subsequent map there are a TON of reflections off the water which is the #1 thing we warn about in the Data Collection guidelines that are agreed to at the time of upload.
That is A LOT of reflections.
From https://www.mapsmadeeasy.com/data_collection:
Minimize the Inclusion of Water
Always in motion, highly reflective, and transparent, water has a lot of properties that make it hard to render well.
Large areas of open water will not likely process well in any photogrammetric application. While it may turn out well enough in a 2D ortho map, water rarely renders well in the 3D outputs and can add unsavory motion related artifacts. If you must include water in a survey area, try to keep some shore structure in place to give our processing something to hold on to.
The images also appear to have been taken directly at solar noon for your area which is also warned against in the Data Collection guidelines. Map Pilot Pro also warns you about this.
These two things together are a pretty good example of how to have a feature matching related zero result.
If you want to try to run it as a Flat Map which doesn't rely on feature matching you could try that if you absolutely must fly at solar noon over water and vegetation.
You can't expect proper results without proper inputs. Please read the Data Collection guidelines carefully before planning your flight activities. They have been the same for years.
