Error during launch of editor/game.. After upgrade from 4.26.1 to 4.27.0

Hello everyone,

after upgrading the engine from 4.26.1 to 4.27.0 (I build from source), the editor crash at launch: 75% 'Verifying ‘NiagaraNodeOp’.

I built the source and the game in ‘Development editor’ configuration. Everything worked perfectly fine with 4.26.1.

You’ll find attached the call stacks.

Below the last call stack lines:

Thanks for your help.

Turns out this has been fixed and is scheduled for a 4.27.1 fix.

For future readers, I just installed the 4.27.1 and everything works perfectly.
