Unreal Engine 4.25 released!

Thanks for the pointer. The log shows that a lot of my blueprints seem to have references to macros that are failing. Here is a snippet of the events that immediately preceed the crash.

The language I find interesting here are the entries that state “invalid macro graph” which seems to tie into the information I get from Visual Studio when debugging the crash. It states that a Read Access Violtion occurs in regards to the enum ‘Graph’ which it sees as a nullptr. The bad news is that doesn’t really give me any clues as to the cause. In the meantime I’m going to have to try moving folders into a clean project individually like you suggested.

If anyone is able to connect any of these dots while I try to work it out please do share.
