Installation Failure 0x80073701 KB5029250

Not off to a good start. 0x80073701 = ERROR_SXS_ASSEMBLY_MISSING which means there are some system files are missing, which caused the update installation failure. You can also try a repair install by running setup.exe from the root of the install.
I wouldn't hold much hope for this or spend any time trying to fix, time would be better spent standing up a new one, patch it fully and migrate the roles or applications over to it.
