I think the problem you've is because Power BI is trying to change the Format for some of the columns, my suggestion in this issue is on the APPLIED STEPS, eliminate the one that says "Change Type", once you do it, the error should no appear, but that doesn't mean i would happen again, you need to look maybe for a string in a column where all values should be a number.
