[Bug]: Cannot perform a Bazel CQuery after setup

[vibbix]

Version

v0.5.0 - latest at the time of this writing on bazel 8.4.2

when running a query like bazel cquery 'somepath("//...", "@com_google_protobuf//:all")' - I am getting this error now after installing toolchains:

I'm wondering if anyone has seen anything like it before. Running bazel clean --expunge etc. doesn't help much here.

I am working on a reproduction guide now.
