Viewing Issues List Results in 500 Error

We just upgraded our hosted GitLab instance to 15.0.0. Now when we navigate to the issues list, we get a 500 error. This happens both at the project and group levels. The output from production.log is below. Has anyone else encountered this or have any suggestions how to get it fixed? Looking at the source code I think it has something to do with the Jira integration. We don’t use Jira.
