Rebuilding Unreal Engine keeps failing

[130s]

So far I've been a few different occasions where I have decided to rebuild Unreal Engine locally. It is kind of a recurring issue to me, and I have a feeling there are tips that one needs to know, to keep rebuilding.

[130s]

One of the cases where I choose to rebuilt UE is #1154 (comment) (where I didn't see an access to FAB on prebuilt UE5.5.1 so went with local-built), then I started seeing UE failing to open a uproject (that was late at night...I forgot what the error was. Maybe the issue in this thread #1143 (comment)), so rebuilding, then hitting compile errors that didn't happen when it was being built for the first time.
