My after effects 2021 crashes after I try to do anything after using the rotoscoping tool.

Ive been trying to do the "Isolate elements with the Roto Brush" tutorial. When ever I get to the part where I've used the roto brush, anything else I click on immediately leads to AE crashing. I'm currently using the latest M1 MacBook Pro 13inch computer and everything(Adobe software included) all seems to be up to date.

I'm not sure what to do?

This worked a charm, thank you very much!
