Crash on project load

I’m getting really tired of this. Hourly crashes and bugs. Now the editor won’t launch my project anymore. It seems to be having some issue with the test-class that I made (BP_BaseBlock_TEST). Is it just me or is everyone having hourly crashes in 4.6.1?

I removed the uasset from the project so I could start the project again. Obviously on project startup I had a load of errors that required to be fixed because of the missing blueprint
