Thanks for the background, but to make progress we really need concrete information. YaST/zypper don’t provide “git master” builds. You can only install what’s in the repos. Installing a specific version like 1.29 would require building it from source. Let’s hold off on that until we know whether the issue is reproducible with TW’s package, or some other underlying cause within your system.
Please run the commands I gave in my last reply and report back.
