After upgrading to 5.1.1, ControlRig Compile doesn't seem to work properly.

After upgrading to 5.1.1, ControlRig Compile doesn’t seem to work properly.
After setting the ControlRig, compile and save, close the tab and open the ControlRig again, it says that compile is necessary.
I thought that the settings were wrong, so I imported only the skeleton, compiled it, closed the tab after saving, and recompiled when I opened it.

Also, the control rig in the sequencer does not work normally, and if you recompile the control rig, the control rig in the sequencer is working normally.
In 5.0 it’s working fine.

I would like to know what part is the problem.
