failed to build and we don't even have a listene

I'm using Jenkins 2.50

After upgrading some plugins all jobs failed, the console log of the job is empty, in Jenkins system log I see the error:

Downgrade the plugins didn't help.

Please your urgent advice.

Apparently the cause of this error is the 'Mask passwords plugin'

I have downgraded from 2.10.1 to 2.9 - the problem was fixed.
