The problem here is two-fold.

1. There is a regression from https://git.libreoffice.org/core/+/d59ec4cd1660410fa1b18c50d2d83b1417a82ddc, which results in the failure to open the link. It is addressed in https://gerrit.libreoffice.org/76778.

2. There is a problem that even when it opens the document, it doesn't follow to the bookmark. That's because, despite LibreOffice is able to open file: URLs with fragment, the code that processes the URL (CSysShExec::execute) calls system function ShellExecuteExW, which internally converts the passed file: URL (like file:///C:/test/test.docx#z1) into system file path (like C:\test\test.docx), and strips the fragment part. No idea how to address that at the moment.

Taking only the first part. I will close this bug after the fix, and suggest that the second part be tracked individually in another bug report.

Thanks for reporting!

let's mark it as a regression then.
@Mike, thanks for taking care of it

As I mentioned, the rest should be tracked independently.

One idea for someone who could try to implement handling the fragment:

we could ask for the system-configured handler application for the file type (using AssocQueryStringW [1]); then take our own executable, and check if the handler is one of our exe files (in the process, testing if two paths are pointing to the same file might be required, e.g. using std::filesystem::equivalent [2]); and in case when we determined that it's this application that opens the document, we could bypass the system call, and open the URI directly, passing the fragment along, which would result in us navigating to it ...

and immediately I see a problem: even when the executable is one of ours, what about possibly configured user environment path? that could result in a different process with different settings, so the workaround would break that. Too many aspects to consider; not something I am going to work on in foreseeable future.
