./x.py install error invalid enum variant tag while decoding PanicStrategy`` #87063
Description
As a developer I should be able to install rust using ./x.py install
However, when I run the command I get...
sudo RUST_BACKTRACE=1 ./x.py install
info: looks like you are running this command under `sudo`
and so in order to preserve your $HOME this will now
use vendored sources by default.
