Linked Files Not Visible in InDesign and Copying Incorrectly Between Layouts

I have been having a lot of trouble the past two weeks with linked artwork not being visible when imported into InDesign. Usually, I was able to cut the artwork and repaste it (in exactly the same place and on exactly the same layer) and it would show up. Now, however,  on a file that I created using Save As and giving it a new name, ALL of the linked artwork is showing in the list of files but for some reason is microscopic—not exaggerating, they literally dots on document when I use the Go to Link from the links sidebar; then, when I start to expland ot to the right size, it behaves as though I'd imported it using Trim size instead of Visible Layers (I did not).  Also, when I try to copy and paste from the original document, the pasted image is the same microscopic as the linked artwork.  All I did was rearrange the elements on the page after creating the new vile so both files are exactly the same size and use exactly the same artwork. So far, it's only happened on this one file but I'm not sure if these are bugs in Illustrator (v 29.7.1 on a Macbook Pro Apple M2 Max with 64 gb RAM).

I have attached a screenshot of what is showing up in my file and what the actual size of the artwork was when I saved the file.
