I would agree with many on here that it sounds like your yeast is the problem.
I see you have tested it, but does seem that something you are doing is upsetting it.
Assume your liquids you are using are tepid, about 35-38c is ideal.
Do be accurate with your measurements too, do not add more yeast, sugar, salt, liquid and flour to your recipe, until like many of us you have learnt to master bread making.
I do use a breadmaker for all my breadmaking. Often using the dough option and then shape into the loaf of my choice. Make baguettes, cottage and sesame long tin loaves regularly using the dough option.
I prove all my bread on my electric range cooker warming plate. Turn that on for about ten minutes and then turn it off and pop the tin or baguette tray on top of a wire rack on the warming plate. That gives the dough a rise to my liking in about an hour.
Here is some of mine I have made this week.
One half/half loaf all done in breadmaker, the rest all using the breadmaker dough setting.
