WWE Crown Jewel 2020 was not held as the event was canceled due to the COVID-19 pandemic. Instead, the event returned in 2021 with WWE Crown Jewel taking place on October 21, 2021, in Riyadh, Saudi Arabia. For reference, WWE Crown Jewel events normally take place in late October to early November, and the 2025 Crown Jewel is set for October 11, 2025, in Perth, Australia, marking the first time the event is held outside Saudi Arabia.

So, to answer specifically, there was no WWE Crown Jewel event in 2020.
