I am getting error while running undercover on mac `file changed before we could read it (Rugged::FilesystemError)`

Question

I am running undercover command and I am getting error as file changed before we could read it (Rugged::FilesystemError) I am on MacOS Sonoma. I have installed gem 'undercover' on Ruby 3.3.0

I checked that the lcov file is present. I even copied that file to another location and used that path in the command. Following is backtrace
