[Bug]: Latest version of libadalang is reporting spurious errors in vscode

Environment

• OS and Version: Debian 12.
• IDE Version: Visual Studio Code 1.127.0
• Ada & SPARK Extension Version: 2026.3.202607051

Bug Summary and Reproducer

Bug Summary:

After updating to the latest version of the Ada & SPARK vscode plugin, I'm getting a lot of highlighted errors in my code (see screenshots). All of these errors seem to be the plugin having difficulties resolving symbols and types. These errors were definitely not present prior to upgrading.

Thank you for your time!

Steps to reproduce: Open project files.

Expected behavior: No incorrect errors shown.
