My Feedback app started to crash under Windows and I didn’t know why. So I opened the Task Manager and found lots and lots of “cefsubproc.exe” orphans hanging around (I don’t know why also). I do remember reading something about a fail in the Xojo/CEF engine in the past where such orphans were not auto closing and that it was said as fixed in newer post 2019 versions. So, please, update the compiled tool (currently listed as compiled using a 2018 version). Thanks.
Workaround: Close apps, reboot Windows.
