I would take Jeff's advice here. Plus, the question about if logical or physical reads are more important to performance tuning can be found by doing a google for "performance...

Apart from the advice above, I'd check all of the disks and any place that the backup file sat for any period of time to make sure that you aren't...

I think the easiest way to do it would be to script out all of the stored procedures that do cross-database communication, drop them, generate the bacpacs, import the bacpacs,...

That is a bit scary and odd... have you reported this to MS? If they are aware of it and it is a limitation of the function, they should document...

Did it work better when run outside of Visual Studio?

I think this depends on the P2V tools and VM host. But this is more of a server question than a SQL question. My advice would have been to not...

According to the MS docs, that shouldn't be happening. As a really random thought - is it possible that an error did occur, just not the way you were thinking?...

As a random guess, does the SQL Agent Service account have access to the file you are trying to rename? If I had to guess I would say It is...

My opinion, I would ask them to do basic troubleshooting to validate that the disk is good. Just because other systems are running fine now, doesn't mean they will continue...

If I had to guess, I'd say that the transaction is not committing.

But my first steps when troubleshooting things like this are to check things like profiler or extended events...
