QtCreator shows "Expression too complex" when debugging with CDB

Question

My environment: Qt5.14.2 + QtCreator4.14.2 + MSVC2017

When I debug programs in QtCreator with CDB, I cannot see the variable's value from using cursor pointing to the variable, but says "Expression too complex"(See the picture below), I googled and test some solutions, including change CDB configurations, download CDB symbols, but none of them works. So hope someone familiar with this could help me out, Thanks for advance.

did you figure out? – Christopherchristopherso

Seems like this bug-report bugreports.qt.io/browse/QTCREATORBUG-24180 is related. It is mentioned that after a clean-rebuild, it is OK (as long as source-code is unchanged). – Asshur

I tried this, but it doesn't work, and I gave up this problem now, because I don't use the debug function often, thanks for your reply – Weeny
