Untriggered Google Sheets Trigger runs and errors

Error description

I have a simple active workflow with a Google Sheets trigger that calls a sub-workflow on new row(s) added. It works just fine when testing and even in production besides this bug.

For some reason this workflow gets triggered ~5 times in a row at random times during the day without any interaction with the sheet/workflow, and throws an error.
When I check the executions instead of a date it also says “Starting soon” and has a 0s runtime, which makes it even stranger.

What causes this behavior and what are its possible solutions?
