Oh boy... What I learned from all my years in IT is that documentation unfortunately doesn't help in like 80% of cases, especially for the purposes of 1st Level Support. Most will rather write, call, ask someone - even if the answer is RTFM. I mean, very often 1st Level Support's role basically IS reading back the documentation / FAQs / checklists to the user on the phone...
You have created absolutely wonderful and extensive documentation uncharacteristic for a hobby FOSS project but any hopes that this would reduce support efforts is naive based on my experience. What extensive documentation usually helps with are the power users or the devs themselves - especially on collaborative projects - who are more likely to seek out information themselves.
Rather than the docs and FAQ, especially for this generation, you'd probably have achieved more with TikTok-Videos.
At this point I think the only way to happiness for you is treating this purely as a
personal hobby project - do whatever works for you and makes
you happy and ignore feature / bug requests that don't affect
you personally.
I know it sounds harsh but you said yourself that you haven't found co-devs and you really don't owe the world anything. You are now basically suffering for the unbelievably crappy design decisions MS have made for W11. Even I started booting more often into Linux after switching to W11. Without EP the interface would be close to unusable from a Power-User perspective and thus it's not unexpected that the project attracted thousands of people world-wide.
P.S. Is the E-Mail address people found out about by any chance the one listed in the README.md on GitHub? I'd remove it. Providing such a direct way for users to interact with you can only cause headaches since it's working by pushing information onto you instead of you deciding when you pull information.
