I think it might be in your settings. Open the workspace which works for
you now and go to GUI settings, check (or leave checked) Save current
window layout as default in general tab and make sure you don't have any
GRASS window minimized and then Save. Try to launch GRASS and it should
work again. I fixed some of these things quite recently, I would have to
check all the use cases again to see if it persists in the recent version.
