[2.1.0-SNAPSHOT]Recorder feature does not work

SikuliX2.1.0 have Recorder feature(experimental).

I confirmed that the feature worked two months ago.
At that time, SikulixIDE version was 2.1.0-SNAPSHOT build#:478.

Today, I get SikulixIDE 2.1.0-SNAPSHOT build#:524.
Recorder feature does not work.
When I stop recording, the exception occurs.
java.lang.IllegalArgumentException: Finder: not possible with: Mat [ 1080*1920*CV_8UC3, isCont=true, isSubmat=false, nativeObj=0x1deb8040, dataAddr=0x29f20080 ]
