Whatever tool is used to create the compiler options checklist seems to fail when it encounters a mingw-w64 GCC compiler version that it does not "know", i.e.:As requested last year when you posted what looks like the same issue can you post instructions on how to re-create this and include the OS and CB version you are using.
When the selected compiler is reverted to a compiler that the tool "knows" it does not go back to the checklist and stays with the blank tab.
