Pressing `?` crashes the console when using vanilla Kafka without Redpanda

I'm attempting to set up Redpanda Console on a Strimzi-managed Kafka cluster. The system appears to work correctly, however whenever I type ? (noticed when attempting to create a JS filter on messages, but also happening regardless of which page I'm on and where), the entire page instantly blanks out.

The console logs throw:

7987.cb8e0bd6.js:2 Error: Minified React error #301; visit https://reactjs.org/docs/error-decoder.html?invariant=301 for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

Followed by a long loop of attempting to "list enterprise features":

^ this is repeated dozens of times

This URL is also hit when I first load the page, along with a number of other endpoints that appear to be specific to the redpanda console, however they seem to have no effect on usage -- everything works perfectly, until I press ?.

Environment:
Redpanda Console 3.1.0, 3.3.0, and 3.5.3
MacOS 15.5
Chrome 145.0.7632.117, Safari 18.5 (20621.2.5.11.8)

Reproduce the crash by pressing ? with vanilla Kafka and inspect the React error alongside repeated LicenseService/ListEnterpriseFeatures requests. Trace the frontend path triggered by the keypress and the license request; done means the console remains usable without Redpanda Admin API configuration and the repeated 501 requests stop.
