Fix NoneType error (missing XXXX method) when opening projects

[areynard13]

This issue occurs intermittently

[areynard13]

Here's some errors that might happen:

0: type none has no method at
0: type none has no method keys

To bypass the error, you can set another file as the main file, then reset main.typ as the main file and the error will disappear.

Not only in prod now, only with some template like report
