ArcGIS Pro 2.8 will only run one instance with a Managed Configuration. Attempting to run a second instance doesn't error but simply runs ArcGIS Pro without the Managed Configuration. Multiple instances worked in 2.7. This is a problem for my clients who need to run multiple instances of the configuration.

I'm surprised this worked for you in 2.7. This never worked for us and we started on 2.5.
If the one or more files are in use that get extracted from the proConfigX file, then the configuration doesn't load because the extraction failed.
There is an issue that is being fixed in the upcoming 2.8.2 update related to extraction and modifying the proConfigX file in a way that is unexpected. Are you modifying the proConfigX file at all?
Thanks for your reply!
My clients are currently using 2.7 and the configuration runs for unlimited instances. When testing the new version 2.8 on multiple machines, we have verified that the behavior is broken in the new version for our configuration.
We do not modify the proConfigX file at all.
Coincidentally, the question of whether multiple instances were supported for us in ArcGIS Pro came up in a meeting today. As described, it doesn't work for us. But if it worked for you in 2.7, then it should work in 2.8.
@UmaHarano, any ideas? Could this be related to the issue that we reported a few weeks ago that is being fixed in 2.8.2?
