Hey so I have been running a custom substrate chain with 3 validators. But recently the chain got crashed with a log election provider failed due to ElectionError::Fallback("NoFallback.")

But the chain continued to run after getting this error in chain and in the explorer stakingElectionfailed

But after some time the peers connected to validators went from 2 to 0. And when I checked the logs, the validators started forking each other and lost the connectivity.

Trying to debug this. Anyone faced any similar issue or any hints that I can use? I'm stuck nowhere now :(
