Error in process filter: Malformed message

[Banzayka]

Hello,

Trying to debug (client: dap-mode, server: code-lldb) various C++ projects (both comprehensive and test-one like "hello, world") and noticed unexpected behavior - debugging works fine until the moment of setting breakpoint. As soon as a single breakpoint is set debugger doesn't launch process anymore with message "error in process filter: malformed message".

I occasionally faced with this issue previously (quite rarely, with almost 0 impact on work), while in the past just clearing breakpoints list and/or Emacs re-start helped, this is not a case anymore - around 50 debugging sessions with the behavior as described above.

Any advice how to fix this will be much appreciated!
