IDEDebugSessionErrorDomain: LLDB provided no error string

Question

Building my Xcode 12.4 project is successful but a popup window immediately appears mentioning "Could not launch project: LLDB provided no string error".. (enhanced question related to "LLDB Provided No Error String" - Problem with XCode).

Following this thread and having tried all suggestions, including i) restarting xcode and computer, ii) sudo DevToolsSecurity -enable, iii) editing Product>Scheme (both in debug and release modes), I have obtained:

with "debug executable" checked: `Could not launch: LLDB provided no error string.

     Details

     Could not launch “testingC”

     Code: 3

From there, I found this post which seems to be relevant in this case, which I tried, resulting in: " can't open file: /System/Library/PrivateFrameworks/LLDB.framework/Versions/A/LLDB", which is normal as I have not LLDB installed.

In this case, what would be the LLDB command(s) to try here? Otherwise, how to fix these errors?
