UE 5.1.0 release Source Build - editor crashes at 83% loading

It builds just fine, but doesn’t launch. Sometimes it just hangs, sometimes I get a popup saying the editor crashed, sometimes I get a popup saying “fatal error.” But it’s always at 83% loading, just after the log outputs “Completed SDK detection: ExitCode = 0”

Anyone know what’s going on here?

Figured it out! The SDK detection thing just happened to be running on a different thread at the time of the crash. That was not where the error was. The problem was actually related to Live Coding. Apparently the LiveCodingConsole project needs to be built before the engine can run, but it’s not a dependency for the UE5 project. Seems to be working fine now.
