I am using Parallels VM version 13.3.0 on my Mac computer, and I have noticed that Windows 10 is running very slowly on the virtual machine since I upgraded my Mac’s operating system to Catalina. The performance of my Mac seems to be normal, and the activity monitor and task manager indicate that everything is running smoothly.

I am wondering if anyone knows what might be causing this issue.

Thank you.
