thanks for sharing the IDs, looking at the first one:
1. I don't see anything immediately wrong in the logs, but I was wondering why this flow run was active for several days since 21st? was this intended?
2. One user restarted this flow run manually multiple times - is this because of this manual approval issue?
3. Could you try creating a new flow run (rather than restarting the current one from failed task run) and see whether this might have been some transient issue?
