Occasional Visitor

Hello everyone, our SP 2013 workflows on our lists are not working since yesterday, monday 19, and workflow history for all records was deleted.
this is the error that we're facing + the workflow history issue:

We haven't made any changes so maybe this is related to the last patch? this is happening across several lists and all web browsers. 
Let me know if you need any other info. or this is repeated and a solution/workaround was found.
all insight is welcomed. 
Thanks!
