Copy/Paste Masking will cause system to freeze

Hi!

I have been having an issue since the last update where when I copy a mask and then attempt to paste it 5+ times, the entire app will freeze and I will have to restart it to be able to click anything. This is frustrating as I just bought a really intense Macbook to make sure my editing (M4 Pro 48 GB memory) was quick and seamless. Crazy that what is seemingly a bug is getting in my way. Does anyone know how to resolve this? 

Version of the app

• 9.0

Platform and OS version

• M4 Pro, Sequoia 15.6.1

Basic steps to reproduce the problem

• Copy mask and paste it 5+ times, sometimes it will take 10+ times

Expected result and actual result

• Expected result is for system not to freeze

Thank you!
