prplrhd,
As an alternative, I would try installing Windows using installation media you can create with the
Windows 10 Media Creation Tool. It'll either be version 21H1 or 21H2, but it should be fine.
If it works you'll still need to install some drivers, which are available on the
file download page. They're drivers for an older version of Windows 10, but they should still work, and they'll then update via Windows Update if there are newer versions. Also, make sure to watch the driver installation video, as the WiFi driver requires a configuration script to operate, and the script and driver have to be installed in a specific way and order.
If the storage on the unit is failing this won't work, of course, but it's still worth a try in the off chance that the storage isn't the problem.
If it
is the storage and it still fails, and the unit is out of warranty, which it sounds like it is from your description (the 2019 reference), there's probably not a whole lot that can be done, and finding someone to replace the storage would likely end up costing you more than the unit is worth.
You
may be able to run Windows from an add on HDD/SSD, but it likely won't be very responsive. I say
may because the T11 isn't really designed to operate that way.
