PS Beta hangs when opening another picture with Camera Raw open

I had several .jpgs open in PS Beta  24.7 m.2245. I opened the camera raw filter and made some adjustments . I forgot to close Camera Raw and used File Explorer to open another .jpg.  It opened it behind Camera Raw.   PS Beta was then locked up.  Camera Raw also. Neither would respond to clicking. The buttons in Camera Raw to Cancel or close it were grayed out. I could move its window off of PS Beta but PS Beta also had everything grayed out. Hitting "X" on the window wouldn't even close it. I had to use task manager to kill it.
