clangd crashes on c++ modules involved project.

[paveltrpn]

I build a recent clang 18.1.0rc boundle, and it have broke my neovim editing pipeline - clangd crashes on startup on c++ modules based project. On old plain source/header pipeline everything works fine. Previous build based on bab01ae works quite fine.

clangd version 18.1.0rc (https://github.com/llvm/llvm-project.git 82e17c1)
