The culprit is

CLOCK: [2023-06-01 Thu 21rr:07]--[2023-06-01 Thu 22:08] =>  1:01

The timestamp is malformed there, which leads to error.

It is still a bug in Org mode that such problem is not handled
gracefully.
Confirmed.

Meanwhile, you can fix that timestamp and other similar problems manually.
You can run M-x org-lint and Org will find suspiciously-looking
timestamps and other potential issues in your files.
