Latest upgrade error

Hi, after clicking the auto upgrade button on the top banner, I see an error on Jenkins website now and don’t know how to roll back or restore the backup. Can anyone give me a hand ??

had stopped jenkins service and hard copy unzipped backup jenkins folder to make it work.
I will blame the Jenkins (2.361.1) upgrade…

Did you follow the upgrade guide?

Generally recommend upgrade all plugins. Upgrade Jenkins. Upgrade plugins again.
