We have a product that we built as a managed configuration. It has been working fine under ArcGIS Pro 2.6 and 2.7.
We recently updated to ArcGIS Pro 2.8 and started getting an “Application has stopped working” crash on startup. We reviewed the dmp file and the error is due to a missing .dll.
This is where things start to get interesting.
When we dug into the issue, we found that something strange is happening during the proConfigX extraction step. All files in the proConfigX file are correctly extracted initially, but then 64 of those files are subsequently deleted. (You can see this happen by opening File Explorer on the AssemblyCache folder; the files appear briefly and then disappear).
Here are the steps to reproduce the problem.
Note that there is some random aspect to this behavior; it crashes most times, but occasionally it starts up correctly. We can reproduce this on multiple machines.
I am unable to attach the proConfigX file as it is 77 MB. Is there somewhere we can upload the proConfigX file so you can investigate?
