Problem

When using VSCodium, the server fails to start with the following error message:

2026-07-27 00:37:29.430 [info] Starting language client
2026-07-27 00:37:29.442 [error] Bootstrap error Error: rust-analyzer Language Server is not available. Please, ensure its [proper installation](https://rust-analyzer.github.io/book/installation.html).

After uninstalling and reinstalling the rust-analyzer extension the issue persisted.

Steps

1. Install the rust-analyzer extension on the target environment
2. Start the server.

Possible Solution(s)

Seems like a duplicate of #21966, except maybe VSCodium/Open VSX have special circumstances.

If it is indeed #21966, reinstalling the extension should work.
