I renamed a custom object and its API name. Now whenever I try to navigate to a specific record I get the following error: "You can't view this item in Lightning Experience. Open in Salesforce Classic."

The object information still shows up in related lists, list views, and reports. I just can't access any specific records.

And indeed, I am able to access it perfectly fine if I revert to classic.

Any ideas what's up? I'll attach a screenshot.
