Can’t open ANY Fritzing file, zip.open(): %d error

Steps I took that resulted in the problem:

Seems like saving a custom part caused something to go wrong. I’ve never had this issue before simply saving to the Desktop/Documents folder for projects.

I can work around not having a custom part, but my corrupt file costs me 2-3 hours of schematic layout. I was finally ready to move on to the PCB layout when I realized I cannot open my project.

I’ve read that I may be able to load my .fz file somehow but I wasn’t able to figure it out with WinZip as it looks like my .fzz file isn’t able to be unzipped?

I am hoping I can somehow open this corrupt file and replace the custom part with an unedited version.

What I expected should have happened instead:

I should be able to open the file days later after my last saved point.

My version of Fritzing and my operating system:

Fritzing 0.9.10
MacOS Ventura 13.7.3

Please also attach any files that help explaining this problem
