[09/11/2020 21:15:08 PM] [Client thread/INFO]: [CHAT] A battle error has occurred! Check the console for details and report this bug to the Pixelmon developers.

Thank you for your report! but this is a known fact. Original ticket: https://pixelmonmod.com/tracker.php?p=2&t=15143

im not using destiny bond, and it dosent tell me that the opponent is either... and even so how do i fix it?

Go into creative and get the NPC editor. Use it on the gym leader and check each of their pokemon to see if they have the move. If they do, remove it/replace the move with another. It might be crashing the battle before the battle text can even say Destiny bond was being used. If you need any further support, I'd advise asking in our Discord.
