Hello @Giovanni Gavazzi ,
Welcome to Microsoft Q&A forum.
Version 17.7.0 adds some new features, perhaps you need to disable this new feature: Tools > Options > Debugging > General > Automatically decompile to source when needed (Managed only). After unchecking this option, please clean your project(remove the hidden .vs folder in your solution folder, rebuild your project) and then debug your project again.
Also, please confirm if this option: Tools > Options > Debugging > General > Enable Just My Code was checked.
BTW, could you please edit your question into English so that we can better help you?
Sincerely,
Tianyu
