Panic on windows:The filename, directory name, or volume label syntax is incorrect

[jolestar]

I run the example on windows and got an error: "The filename, directory name, or volume label syntax is incorrect". I try to change the ipc file path, and also not work.

 wmic os get version

Version
10.0.18363

This is the backtrace:

Are you using a pipe name in the \\.\pipe\this_is_the_name_of_a_named_pipe format? You will get ERROR_INVALID_NAME if you don't use the right format.
