stlink: Unable to flash any Nucleo board

I am unable to flash any Nucleo board using version 1.6.1 or the current dev version while the same time version 1.6.0 works just fine. Is it possible I screwed up the build? But build is so simple that it is nearly impossible to break anything. The only thing I did differently: I used cmake which comes with VS Studio but I do not see how this could cause a problem. Version 1.6.0 built the same way works fine.

Boards tested: Nucleo-F303K8, Nucleo-F767ZI, Nucleo-F746ZG, DISCO-STM32F769NI Windows 10.0.19041
