Both are me, for some reason Thunderbird on Android decided to use "Boulder" which is Google account name. Hope this won't happen this time. Please bear with me while I debug identity settings.

We still can debug this, but you'll have to blacklist the drivers that make your system not boot (and lose the graphical interface in the meantime, or rely purely on integrated graphics during debugging if they are present) and try iwlwifi through the command line. In the worst-case scenario, you will need a USB with Linux distro ISO on it, and a guide on how to use chroot. Keep track of the changes you will have done, that way it will be easier to restore the system.

If you use NetworkManager for wireless (you likely do, most Linux distros do), you can use nmtui to connect to Wi-Fi from there, which may be useful for further testing.

Hope it's not NVIDIA (it will surely be NVIDIA),
