Jo the Cannibal Bossfight Glitched

I just encountered this on PS5.  I assume it's related to Jo the Cannibal not being able to deliver all of the scripted dialogue prior to the boss fight, because I originally just fast-traveled to the nearest meditation spot and then ran past the droids and bounty hunters that were standing in my way.

My solution was to first backtrack and kill all the enemies I had skipped, in order to get the dialogue to play.  I noticed several of the enemies had developed minor glitches of their own, such as refusing to leave a hut or roof, so I had to search each section thoroughly to make sure I got them all.  I did this all the way back to the entrance of the Lucrehulk, which triggered additional dialogue I had missed of Jo the Cannibal telling the raiders and bounty hunters to prepare for Cal's arrival.

Once I was sure there were no more enemies to kill or dialogue to trigger, I saved at a meditation spot WITHOUT RESTING to reset the enemies and quit to the main menu.  Once I hit continue, the enemies were all reset anyway and I was able to take the zipline shortcut directly to the boss fight and Jo the Cannibal finally jumped down to join the battle.  I actually tried clearing out the enemies and quitting several times prior to this but each time I rested out of habit before exiting to the main menu.  For whatever reason, it appears that resetting the enemies also had the effect of resetting the glitch.  Hopefully this method can work for you guys too.
