I'm attempting to transfer my previously formatted paper which was in the Springer Nature format to IEEE Access, and despite there being no error whatsoever in the original, the new document marks every figure and table with "illegal unit of measure (pt inserted)" and also an "undefined control sequence" errors. I've looked at the documentation and even copy pasted the code on the Overleaf website, still produces the same error. Here is my code:
