Description

including any calls to I2C functionality on ST_NUCLEO64_F091RC causes program to not run.

Detailed repro steps so we can see the same problem

1. Run provided code in debugger LED flashes

2. Stop program (can start/stop many times)

3. Un-comment Debug.WriteLine(I2cDevice.GetDeviceSelector());

4. Run program, doesn't appear to start

Other suggested things

Sample code attached

Expected behaviour

Should be able to start/stop program multiple times
