The solution
The door locks before arrival
Impossible to reach quickly
is there a solution

You tried to write a poem? (Just joking)

Can you post an image from the door? It must be less than 500kb to upload the screen capture, and post the name of the level, are you sure is a bug? Have you seen a wallthrough?

Maybe noclip through the door?

Are you referring to this issue?

If it's the case, then it's probably not a bug and the solution lies in the level.
