Hi,
you are using a Release Candidate version, not a stable version.

PleaSEW remove the installed c4doctane version and upgrade to 2021.1.4-R4 new stable version.

You can find it by visiting your personal Downloads area:

Then copy paste everything in a new scene, and use the latest stable version to edit the scene.

ciao,
Beppe
