Same problem here.
It is annoying, that there is no response to the click at all.
There should be some message displayed.“Cannot start. Try later. Try this and this”, let it be “General protection fault 0815” - but nothing at all? Just ignoring the user and its action?
I think, it is always a bad idea to release a fix just before Christmas or on Friday before a bank holiday…
PS: @Agusagaz - thank you for your suggestion to “Repair”! It worked for me.
