Hi Cedric,
I'm only experiencing issues when using WebEngine functions. That is, the object I'm interested in is created, but the first function to be used encounters the error I mentioned, leaving the program incomplete.
I fixed the file path reference "/config/mixer.config" and there's no issue about that. Like you, I intended to tackle debugging the brutalist way :) However, the serious problem is that in this process, I'm interacting with the Qt5WebEngine library, through which the debug path also passes. Each build of it takes around 10 hours for me, practically making the debugging process impossible.
In any case, I appreciate your response.
Thank you, Hamed
