I right click on an individual test case and click debug this test and it seems to start loading the debugger and then nothing and the console shows:

18:32:34: Debugging C:\CODE\SBGSource\build-SQTest-Desktop_Qt_5_12_5_MSVC2017_64bit-Debug\debug\SQTest.exe "-gtest_filter="\""TagTemplateTest.BasicGlobalLabelsLabelLinks"\""" --gtest_break_on_failure "-gtest_catch_exceptions=0" ...
18:32:42: Debugging of C:\CODE\SBGSource\build-SQTest-Desktop_Qt_5_12_5_MSVC2017_64bit-Debug\debug\SQTest.exe "-gtest_filter="\""TagTemplateTest.BasicGlobalLabelsLabelLinks"\""" --gtest_break_on_failure "-gtest_catch_exceptions=0" has finished.

without the debugger stopping at the breakpoint even if put at the constructor of the fragment. ( and it's not crashing before that as if I run it it runs well in to the test up to the assert I'm trying to investigate)

This is a regression.
