Unknown error while debuggin rust application in VS Code - rust

Question

I am trying to debug a fairly large rust project in VS code.
The launch.json has this:
{
"type": "lldb",
"request": "launch",
"name": "Debug executable 'rpfm_ui'",
"cargo": {
"args": [
"build",
"--bin=rpfm_ui",
"--package=rpfm_ui"
],
"filter": {
"name": "rpfm_ui",
"kind": "bin"
}
},
"args": [],
"cwd": "${workspaceFolder}"
},
But when I try to run the application I get the following
Finished dev [unoptimized + debuginfo] target(s) in 9.53s
Raw artifacts:
{
fileName: 'c:\\Users\\ole_k\\Desktop\\rpfm-master\\target\\debug\\rpfm_ui.exe',

kind: 'bin'
}
Filtered artifacts:
{
fileName: 'c:\\Users\\ole_k\\Desktop\\rpfm-master\\target\\debug\\rpfm_ui.exe',
name: 'rpfm_ui',
kind: 'bin'
}

}

Debug adapter exit code=0, signal=null.
I have also seen this:
PS C:\Users\ole_k\Desktop\rpfm-master> & 'c:\Users\ole_k.vscode\extensions\vadimcn.vscode-lldb-1.5.3\adapter\codelldb.exe' 'terminal-agent' '--port=49628'

[2020-06-27T20:29:08Z ERROR codelldb::debug_session] process launch failed: unknown error
If I run the application from the terminal inside vs code (cargo run --bin rpfm_ui) it works.
There are some external dependencies which are in folders outside of the root folder.
I can debug other projects in the solution which share a lot of the code, but not the external dependencies.
I can debug other projects.
I am running as administrator.
Any ideas on how to resolve the issue?
