Watch out for an old VC++ runtime

 VC_redist.x64.exe

 For C/ C++ applications the VC++ runtime needs to be installed on the computer. The other day we experienced crashes when a component developed with a late version of VS2022 was crashing on a fresh installation of Windows 11. It turned out that this Windows 11 still uses an old version of the VC++ runtime which could crash the application (most notably in grabbing a std::mutex lock). After updating the PC with a recent version of 'VC_redist.x64.exe' the problem was solved.
