Read timed out error-... bug? (SOLVED)

“Launching Local dmengine - 127.0.0.1:49208 failed:
Read timed out”

when trying to build (Project-Buld) or rebuild.

Any help?

Happens all the time? Have you tried restarting the editor and/or computer? When did it last work?

Restarted and it all worked fine.

I sometimes get nervous about saving all and restarting if I have an error that stops the build, just in case I save the thing that causes the error. But in this case it was not a problem.
