MySql using 60+ GB of memory to run one query

Hello all. I am new to MySQL (previously used SQlite3) and am trying to run the below query on my mac (version 12.6), but it is using over 60GB of data to run and I am running out of disk space. I am running MySQL version 8.0.3. I have tried optimizing parameters in the options field but have had no luck. Any assistance related to this issue would be greatly appreciated. Thank you!
