i tried using code lldb launch config i found on osdev wiki but symbols are still not loading

{
            "type": "lldb",
            "request": "custom",
            "name": "Custom launch",
            "targetCreateCommands": [
                "target create --no-dependents ${workspaceFolder}/target/x86_64-unknown-uefi/debug/os.efi --symfile ${workspaceFolder}/target/x86_64-unknown-uefi/debug/os.pdb"
            ],
            "processCreateCommands": ["gdb-remote localhost:1234"]
}

i tried checking the pdb file using llvm-pdbutil and it seems fine (at least as much as i know)

when i tried using wsl2 it didn't throw this error but the symbols were still missing, same thing happened when tried compiling with RUSTFLAGS="-C debuginfo=2"

This is on Windows release 18.1.5 with MS DIA PDB parser.

When forced to use NativePDB parser (LLDB_USE_NATIVE_PDB_READER=1) it works quite all right.
