1. No--"X risks the danger of Y" means that if X is done then the undesirable event or state Y might occur. So Y won't occur for certain, but there's some possibility that it might, hence a risk that it might--one would be taking a chance. 2. "a mute a-signifying state" is an a-signifying state that "says" nothing.

1. No. 'results in' implies a 100% chance of ---> 'the danger of collapsing...'. By using 'risks' the writer is saying two things: 1. There is a chance or possibility of --> 'the danger of collapsing'. This chance is not certain. 2. The word 'risks' ALSO suggests that if this outcome ('danger of collapsing...', here) occurs, then this outcome will have a non-positive outcome. ie. The outcome, IF it occurs, won't be what is desired. 2. "a mute a-signifying state" I'm not certain here, but this is my interpretation ... 'mute' can mean being silent or having an inability to speak. 'a-signifying' can mean the inability to transfer or give meaning. 'state' means here the particular condition of something at a specific time. Put together, my best guess of "the danger of collapsing into a mute a-signifying state." would be "the danger of falling back/collapsing into a non-communicative (silent) condition where meaning can't be produced.
