Equation Errors

Since updating to Solidworks 2024, I will occasionally have some of my parts show up with red errors. When I go to find out what's causing these errors, the equations folder is red. The "What's Wrong" dialog box gives the error in the screenshot. However, there are no equations or global variables in my part. If I open the part directly and do a rebuild, the errors go away. When I go back to the assembly the errors will go away if I still have the part in question open, but the errors come back if I close the part first. Can anybody explain this? Is there a fix?
