Converting journal file from Trelis 15.1 to 16.1 HDF5 error

I have a journal file which runs correctly in 15.1.3 that I am trying to run in 16.1. When attempting to do simple geometric functions (subtracting volumes, webcutting volumes), I often get HDF5 errors. What does this mean and how can I fix it?

I got that same error also when I try to merge and imprint all my volume. I am what it means also, hopefully they can help us.
