Looks like this is because your writing a function outside of a class and it's trying to find the class header to resolve any namespaces

[neild3r]

Similar to #208

[AnrDaemon]

Backtrace seems very similar, yes.

[neild3r]

This should be fixed as of v2.6.1

[AnrDaemon]

Can't you detect outer block start when in editor? Then you won't need to back scan N lines.

[neild3r]

Admittedly I haven't had a detailed read of the VSCode API for a quite some time but last I checked there wasn't a simple way to do that. If you know how I'm all ears.
