Current behavior: just about every window (including non-VS Code windows) hard-crashes

Expected behavior: not that ^

Relevant log output

No response

Which area(s) are affected? (Select all that apply)

Not sure

Additional context

This does not happen when:

• running the sidecar executable (./ide-sidecar-X.Y.Z-runner) in a standalone terminal and activating the extension
• running the sidecar executable and then running make quarkus-dev in another terminal

[shouples]

Unclear if other combinations of running processes/extensions and our extension will cause this same behavior, but using make quarkus-dev was the first time we witnessed the above.

[jlrobins]

Issue happens only for us extension devs who are running sidecar in quarkus dev not having enabling access token filter AND that sidecar is not the version the extension expects.

Fix is in progress.
