Hi,
Thank you for the attached files. As I can see, the CPR file is 5.5MB only, not 2.4GB.
But as far as I can see, you are using some Arturia plug-ins, right? There is an known issue in the current Arturia releases. The plug-ins store some data, which causes the project size increase.
I hope they will fix it soon. Please get in contact with them.
