[RodgeFu]

the server path is set which seems invalid. but anyway we shouldn't crash.

@mzhongl524 , could you help to have a quick look so that we can understand the impact of the crash? thanks.

[RodgeFu]

Confirmed that it's the crash of lsp server because invalid tsp-server path is given. Close as dup of #6475 . thanks.
