Application Memory running out with Topaz Video

I have a Mac Studio M4 Max with 36 GB Memory. Using Topaz Video for 3 months with no problem. In the last week every time I try to use the program it starts OK then always ends up failing and states " Run out of Application Memory" I've cleared all caches, ran "sudo purge" in terminal but to no joy. Can anyone help me sort out this problem please?
