cut and paste slow

Hello, when cutting and pasting a small object in Corel 2017, it takes about 10 seconds to copy, and the same to paste in one file. In another file the same object cutting and pasting is under a second. When cutting and pasting (as a test) the same object from Corel 2017 to 2019, the file takes forever and slows down my machine.

Deleted Trash and Temp files, rebooted, etc. I have a pretty fast system and clean.

Any thoughts?
