Adding `GIO_USE_VFS=` to the end of `a_envp` (starting on line 56), fixes that for me on Fedora 34 with polkit-0.117-3. If anybody knows why that makes a difference, I would love to hear.

Ran into this while writing my exploit. I explain it here https://github.com/v-rzh/CVE-2021-4034/blob/master/README.md... :)
