Description
When adding a default route via ZT IP address of one of the nodes, Windows will not use that default route. The same default route does work on Android. I've seen issues marked as fixed before about this same problem, but on Win11 the problem is not fixed on 1.12.2. Windows keeps using its own default route. The ZT default route gets added with a wrong subnet mask and metric. This also breaks other routes via the same ZT node.
Windows build 22621.2283
ZT 1.12.2

Research direction
Start by reproducing the default-route setup on Windows 11 build 22621.2283 with ZeroTier 1.12.2, then inspect the resulting route subnet mask and metric and compare them with Android behavior. Done means the ZT default route is installed with the correct mask and metric, Windows uses it, and other routes through the same ZT node continue to work.
