In Season 3 Episode 1, The Rickshank Rickdemption (2017), a journey through Rick's memories shows that Beth and her mom were killed by an explosion left by another Rick, this episode shows that Rick went hunting through the multiverse for that Rick. However, in Rickshank Rickdemption, Rick reveals that this backstory is a complete fabrication by him to mislead the Federation agent, a misdirection which is the key to Rick's escape. This episode treats that story as canon, that it really happened after all.
During the Rick's Backstory montage, the Smith house can be seen with the usual crack in the driveway and lawn from Rick Potion #9 (2014), right before Rick crashes his car into the garage. But this is a memory, essentially a flashback, showing Rick joining the family in the first place before the Pilot (as indicated by Beth crying upon seeing him, since she was seeing him for the first time in years). As in, this is before the events of Rick Potion #9 when that crack was created. There should be no crack yet.
