The same issue as occurred to me too and I pressed ignore which kept leading me to the bad ending
Please look at this comment! ^^
Clicking "rollback" will just revert the game back to a playable moment in time; it won't let you bypass the error. Clicking "ignore" will let you bypass the error, however, it's likely that it will crash the game as well.

Well because press 'ignore' will automatically lead you to choose 'stay at Ren's home' and get the BAD END. Therefore I delete all the saving files and found out this problem solved. Hope this can help you!
