• Operating system (and version): linux mint 22.2
• Version of tool extension you are using: 2025.2.0

Behaviour

Expected Behavior

no crash

Actual Behavior

looks like it's because this LanguageServer class has been moved/deleted/renamed in pygls 2.0

AttributeError: module 'pygls.server' has no attribute 'LanguageServer'

Reproduction Steps:

1. set "pylint.importStrategy": "fromEnvironment" in .vscode/settings.json
2. install pygls 2.0 into the current venv (uv add --dev pygls==2.0.0)
3. restart vscode and open a python file

Did running it from the command line work? yes

Extra Details

my project depends on pygls so i don't want to have to downgrade it. this extension should probably use its own bundled version of pygls even when pylint.importStrategy is set to "fromEnvironment"
