CPU profile tool is not working in ROS 6.5 mipslbe

CPU profile tool is not working in RouterOS 6.5 on my RB 951G-2HnD . (firmware updated to 3.10)
In winbox the profile window titled runnning but the window is empty.
It is no response if I use ‘/tool profile’ in terminal.

But cpu profile tool working in meta-router. It even shows a window that can choose between all,cpu0,total.

BTW, 6.5 x86 within VMware works fine.

profiler is timer based, if you are running metarouter then CPU time is split between 2 hypervisor guests (guest with hardware access permissions and the guest) If the profiler measurement has to happen when guest does not have CPU it will report nothing. After reboot this can change if timing is right.

Thanks, it works after restart the router.
