How nice... So it looks like exception propagation is broken in your setup and it's hard to guess why without investigating a little. Of course it's a bit tricky to do, especially on Windows. Can you upload somewhere a package containing the executable, libgcc_s_dw2-1.dll and libstdc++.dll from GCC 11, as well as libstdc++.dll from GCC 10 and post the URL here?
