An error was encountered while writing the output file. The output destination could not be found.

I was trying to export my project from prem pro, so it went into media encoder and while i was trying to render it:

An error was encountered while writing the output file. The output destination could not be found. Check that the output directory still exists. If the output directory is on a network or external device, check that the connection is active.

popped up. How do I fix it? 😕😕 I used an adobe after effects project file and its called Untitled.
