Hi, I’m new to robot framework but i noted that .robot or .resource files with a \*\*\* settings \*\*\* section in start of a file with documentation throws this error for me. **Error collecting Robocop errors: Unable to get mutex for: c:\users\user.robotframework-ls\specs\v2\769da057\_5.0.1\builtins\xml.libspec after 30 seconds.** ![image](https://europe1.discourse-cdn.com/flex005/uploads/robotframework1/original/2X/1/16c78e29c5941822ef7e5eb4a2894bbd112a6e59.png) To get rid of the error, i have to take the documentation descriptions away fully. So if i leave resource definitions only, the error gets away (but only after restarting VS code). **I use** VS Code 1.70.2 Python 3.10 **VS extension →** Robot framework language server v.1.0.0 → last updated 17.8.2022 (17th of august). Am i doing something wrong or do i miss some extension needed ? ---

Ok, seems like documentation removal did not fix the problem. its back again… ---

I experience this as well. I believe it is the [Robocorp LSP](https://robocorp.com/docs/developer-tools/visual-studio-code/overview) (which, IMO, is generally pretty great) + [Robocop](https://robocop.readthedocs.io/en/stable/). When I hover over the red squiggly line, I (mostly) get this error message: `Error collecting Robocop errors: 'Variable' object has no attribute 'error'` I honestly don’t know how to get this error to go away. 😒 ---

I would suggest creating an issue for this in the GitHub repo for the LSP. ---
