> Try with this debugger configuration: Here, the debugger is interpreting everything. Also make sure to set your breakpoints before starting a debugging session – applying them while debugging can sometimes fail. If none of that works, set ENV["JULIA\_DEBUG"] = "DebugAdapter,DebugEngines" and try again – if you can paste the output into a gist and post a MWE, I can take a look at what’s going on.
