Here is a lazy man suggestion. This happened to me earlier with the Hive transaction somehow causing issues with Steem transactions including posting. Here is what I did.
I started using two browsers. Steem and Steem Keychain on Google Chrome while Hive and Hive Keychain on Brave. Never faced that issue again. Now, you may argue that it is a node problem and not really dependent on browser then the question is how did a Hive command (transaction) initiate a Steem action? So, until things are fully sorted out. Follow this idea. Just a suggestion.
