Unexpected behavior of terminal pop-up

Nobody has claimed this yet.

### How are you using the lua-language-server?

NeoVim

### Which OS are you using?

Windows

### What is the issue affecting?

Other

### Expected Behaviour

No terminal pop-up.

### Actual Behaviour

When I access file or :wq save and exit .lua file, terminal(not in neovim) will pop-up.

### Reproduction steps

1.install mason in neovim
2.add lsp lua_ls
3.open or close lua file

### Additional Notes

> Client lua_ls quit with exit code 1 and signal 0. Check log for errors: C:\Users\%username%\AppData\Local\nvim-data/lsp.log

my username is non-ASCII, and the log shows that it can't identify my username.

### Log File

> [ERROR][2024-08-12 19:05:02] .../vim/lsp/rpc.lua:770 "rpc" "C:\\Users\\鍚曠菠钂橽\AppData\\Local\\nvim-data\\mason\\bin\\lua-language-server.CMD" "stderr"

Start with the reported Windows reproduction using Mason's lua_ls entry and inspect the C:\Users\%username%\AppData\Local\nvim-data\lsp.log output, especially the lua-language-server.CMD path and non-ASCII username. Done means opening or saving and quitting a .lua file in Neovim no longer opens an external terminal, and lua_ls does not exit with code 1.
