[Crash] Cannot re-open project (again)

I was under the assumption that the major headline release of 4.14 would have far more stability than I’ve been seeing. Most frustrating lately is the sheer amount of crashes - but even worse is when the editor won’t open back up again. It’s incredibly frustrating. This has happened enough that I regret updating to 4.14 and am considering re-creating my progress in 4.13 again.

Last night before bed, I saved and reopened my project successfully. Today, I cannot even open the project again. I can’t think of there being any condition in which the edit can’t reopen. There’s no point in the upgrade if the editor can’t stay open when the complexity of my project is rudimentary at best.

Here’s my error log and machine id.

The only way to get past this is to replace backup files to the most recent uasset saves. Whatever the problem with a blueprint may be - it shouldn’t prevent the editor from opening - that’s what compile errors are for.
