Please file a bug report against lldb reporting this failure log, and as many details as possible
(lldb) symbol file 'c:\Users\aylon\Documents\os\target\x86_64-unknown-uefi\debug\os.pdb' has been added to 'c:\Users\aylon\Documents\os\target\x86_64-unknown-uefi\debug\os.efi

```
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 didnt throw this error but the symbols were still missing, same thing happend when tried compiling with RUSTFLAGS="-C debuginfo=2"
