So instead of troubleshooting you went straight to "oh my god this is the end of days!" These seem like obvious user error or at worst bugs.
Not to mention you've pivoted from Copilot in Notepad to Copilot in general. Which are not the same thing. Copilot is a brand name and various instances of it are not connected at all.
Unfortunately, you started with the first 2 paragraphs, so clearly you're more interested in moaning at me. But this is the internet, so that's fine. I already expected it. In fact, I'm disappointed. You're going to have to try harder.
