ERROR "Unable to resolve the name images.roi.Line"

Hello,

I've used AppDesigner with Matlab release 2021b and everything worked fine. Due to some circumstances I had to move back to the relesase 2021a and now this simple codeline:

line = images.roi.Line()

throws an error "Unable to resolve the name images.roi.Line". Do you know what can cause this?
