This happens with realtime render.
Windows 10 home, 32gb ram, amd
Tried disabling various cloud services from the system tray to no help.
Please check the videolink
EDIT after disabling the spotify thing from the systray, the render worked until almost the end, then had the hickup and went into this “noise”-mode.
I establsished the fact that the file still plays back, as I let it run the few final seconds until the end, it then stopped and started the next render.
