URL: https://github.com/apache/airflow/issues/42456
### Apache Airflow version
Other Airflow 2 version (please specify below)
### If "Other Airflow 2 version" selected, which one?
2.10.0
### What happened?
An OTEL Collector exception caused the scheduler to terminate unexpectedly.
```
[2024-09-13T14:12:12.681+0000] {scheduler_job_runner.py:1001} ERROR -
Exception when executing SchedulerJob._run_scheduler_loop
Traceback (most recent call last):

line 283, in datetime_to_nano
return int(datetime.timestamp() * 1000000000)
AttributeError: 'NoneType' object has no attribute 'timestamp'
```
The exception was due to the processing of an executor event where the tied
task instance start_date attribute did not have the expected type of datetime.
### What you think should happen instead?
Instead of raising the exception and causing the schedule to terminate, the
exception should be caught and an error log to be generated.
