Keil cannot step through C code

[jeromeDms]

Hi there
I just bough the Nuvoton edition of Keil ARM compiler as I have to develop on the M471 MCU.
When running your USB Host examples, I cannot step the debugger through C code but only through disassembly.
The debug informations are checked in the settings, I did not change anything from your example project.
Any help would be appreciated
I'm runnning Keil latest version, on parallels desktop software running windows on Mac, I tried Win 10, Win 11, Mac M1 and Mac Intel.
Thanks

Replying to myself.
Problem comes from Keil running on parallel desktop for MacOS.
It seems there is an issue with source files PATHs, if they are located in the main directory it just works fine (can set breakpoints), if they are located in a sub directory or outside the main Keil project directory, the linker is not able to retrieve C code to enable debugging with breakpoints.
