What is the error message you received when using the batch action? What page are you in when you received the error message?
If the Batch action you're referring to is under the Vendor tab, I'd recommend contacting our QuickBooks Customer Care Team. There are a few reported issues about this and our engineers are already working for a fix. One of our phone support representatives can add you to the list of affected users. They'll keep you up to date about the progress on this issue.
Meanwhile, we can do browser troubleshooting steps if you're referring to a different Batch action button. They might be caused by piled-up cache files.
We can use a private browser since it doesn't store cache files. Then, try using the Batch action function again. Using other supported browser can be a good alternative to try the troubleshooting steps, too.
You can clear the cache storage of your regular browser if there's no problem when using the Batch action in the private or other ones.
If the same thing happens, you can reach out to one of our phone support representatives using the contact information I provided earlier. They can further investigate this for you.
