always terminated when start debug

[echogqq]

ocaml-compiler:4.12.0
learlybird:1.1.0

when I start debug, It always stop at some lib function exception. The I add breakpoints at the main function. Press continue(or step in, stop over), the debugger stopped. here is the log:

I had the same issue and it got resolved by setting

(map_workspace_root false)

in my dune-project file. Does this help?
