Hi Thomas,
AFAIK the error message is displayed when the zip_open function of the 
libzip library, used by QGIS, fails to open the .qgz project file.
Are there other related error messages in the Log Messages panel?

Since you think the issue may be related to the recent OSGeo4W packages 
update, have you tried to downgrade the libzip library using the OSGeo4W 
Setup program to the previous version?

Best regards.

Andrea
