When launching Cortex-Debug in VSCode, the command gdb-set mi-async on triggers the error Failed to generate gdb commands: Cannot change this setting while the inferior is running. As a result, I cannot debug on VSCode. Full error report below.

I checked for the error in other sources, and it is related to not being able to halt the inferior.
However, if I connect the debugger to the remote target in the command line, halt the execution, and try to run set mi-async on, the same error message is displayed.
I wonder if the change of settings has to be done before the target is attached. Any leads are appreciated.
