I generally recommend enabling logs (through `log enable lldb
<category> -f ~/somefile.txt`) and then work back from there.
The logs tend to contain a lot of informations so I'd try with few
channels. I'd start with `formatters`.

To get a full list you can try:
(lldb) log list
(lldb) log help

This helped me to solve a few issues I would've otherwise had no clue
where to start (once I understand the context from the formatter, I
generally grep in the source code & set breakpoints).
Don't hesitate to ask if you have other questions.
