EPGZ files does not open

[dienal-san]

• Operating system: Fedora 31
• Pencil version: 3.1.0

Hi All,
Recently I reinstall my laptop. Migrated all the epgz files to the new images. After doing that I was having multiple issues opening the epgz file, but after a few minutes they were opening. Now one of the files where we have the main source pages is not opening any more.
I tried to check the development screen and it does not show anything on it. I have looked around and I am not able to find out a way to troubleshoot.

One idea that I had is to create a new project and migrate the files to it one by one, but compressing an epgz file is not working.

I appreciate any help provided.
