attempting to perform a "rename symbol", I am getting the following error:

File not found (\"C:\Users<valid path>\file.go")

this happens on workspace or individual file settings.
I've tried changing the environment variables to remove the C: but everything stops working then.

note the backslash before the quote.
cannot seem to find any other settings that impact this.
