Nintex for SharePoint 2019 Limitations

I was wondering if there was a limit to how many workflows on SharePoint can be ran at one time. For instance, I have a workflow that runs on item creation in a SharePoint list. If another resource creates 2400 items in that list, that would mean I have around 2400 workflows running at one time. This appears to be an issue as I do run into many items in that list that show a workflow status of “In Progress” and are stuck with that status for an indefinite amount of time. Any assistance on how to navigate this issue would be greatly appreciated.
