The operation can not be completed because of an unknown error. [IABD]

I'm having issues with a large Illustrator file. When I first open the file I get the error in this post subject and then I'll get a second error that says "An error occurred while processing the appearance of an object." I will also get the error in the subject when I try to use specific tools or commands. For example, when I try to reflect an object I'll get this error. I'll always get the error and sometimes the command won't work the first time but will work if I try it a few more times. I'm using 28.4.1 but this has been an issue for awhile now. I'm also on a Mac running MacOS 14.5. I have tried creating a copy of the file and resetting my preferences. I have also tried creating a new document and copying the content into that new file and still get the same error.

I do have a couple of objects that were copied from older documents. The objects are a grouping of gradients and PNGs that create the appearance of a spun metal texture. I'm wondering if that could be the issue.
