[Help Needed] Lost Access to Save After Build Disabled (Need 42.12.3 Beta)

[final dome]

Hi, I really need help.

My name is Umut (Atrix on YouTube), and I’m currently working on a 100 days CDDA challenge video for Project Zomboid. I’ve been recording and streaming this run for a long time.

After the recent update, the build I was using (42.12.3) got disabled due to critical issues, and now my save is no longer compatible. I cannot access my world anymore.

This save is extremely important to me because it contains a lot of recorded progress and content.

Is there any way to temporarily access build 42.12.3 (beta), or receive a beta code to enable it? Or any safe way to load/recover my save?

I completely understand the risks — I just need access to finish my project.

I can provide my save files if needed.

Thank you so much for any help. @woven tartan

You can try uploading your save so we can try transferring it to 42.15+.

I tried, but because it's on CDDA, my character starts dead, and the house I last left is burning when I restart. Additionally, updating my save file to the new version resets my hideout and all map items.
