I had issues regarding the verify process of the 4.7.3 install. After a reboot I wanted to open my project in 4.6.1 and it freezes. It has frozen and have had to force a reboot on the computer.
Hello ImperiumPandemonium,
Are you able to open 4.6.1 or 4.7.3 at all? Also, are you able to open your project in either versions of the editor? Do you receive a crash reporter when the editor freezes?
Please provide as much information as possible, so we can assist you further. Looking forward to hearing from you. 
No crash report when it freezes. Everything but the mouse freezes but Nothing else works. When I reboot the computer everuthing seems fine until I start the project. I still have verifying issues and have followed the troubleshooting guidlines and every answer on the hub without a solution to my problem, and now problems.

I fixed everything by myself, just needed some time with the log files.
Hey ImperiumPandemonium,
I’m so happy that you’ve been able to resolve your own issue by searching through the yourself. Would you mind providing us with the information you took to solve your situation? It may come in handy in the future for others in our community.

I had downloaded some free assets with a demo project to try online and added it to my content folder (in my 4.6.1 project, but not through migrating). Some large files must have had corrupt references when trying to load, so it froze.
Now before I tried again I took another look at the last 2 crashreports I had gotten before it came to the point that it just froze. I saw these imported assets and blueprints being referenced somewhere in the report. Then I went inside the content folder and deleted every files I had added and it worked like a charm.
Hey ImperiumPandemonium,
Thank you so much for providing me with resolution to the issue you were experiencing. I’m going to look into this a bit further and see if there is an actual bug hidden in this.
Cheers!
