I have tried for the last few days to utilize the Jira-provided (built-in) "Time Tracking Report" which I have successfully used for the past month. When I configure it and hit 'Next' the result is always an error:
Error Type: 500 - Internal Server Error

Per the warning on that page, I have checked the Statuspage and there is no known outage at Jira. I can't open a Support Request because I am on the Free plan.
Is this just me having this problem?
I have tried all the various configuration options (there aren't many) in case the issue is arising from one of those. That doesn't help.
What else can I try to do differently? Is it possible some data I entered recently into the worklog is causing the error?
Here is the report I am referring to:
