when upgrading to scrivener 3 beta, the files appear empty but the titles of the different chapters are OK.

[kaini]

the .rtf and .txt texts are in the file of my novel project, but when opening scrivener 3 beta, only the chapter titles appear.

no error message appears in scrivener 3, except with automatic save:

could not save the project document. Error: 'Could not open RTF file for writing. To avoid losing your latest changes, make sure you have enough space and write access on your storage device. You can create a copy of your project into another location using the menu File > Save as. You might also try to compile and save to RTF od DOC format to avoid losing your latest changes.
