Copilot cannot read yaml/yml file when set YAML Editor as default

[bachden]

I'm using copilot (by github) plugin in eclipse 2025-06. Anytime when I open a yaml/yml file with YAML Editor, the file appear in context file of the copilot chat panel, then copilot response as below. It's new issue as I was using copilot and yaml editor for a long time. Can you take a look and investigate?

Hi. I think this is not an issue with Yaml Editor, but file access - The lsp4j complains about a missing file - and the access is done by file system.
I would check if the file at the exception is really not existing. If it is existing - it looks like windows - maybe the lsp4j excuting instance has no access to the file?

But i am pretty sure it has nothing to do with the Yaml Editor plugin.
