Running Windows 10 VM disturbs Mac Browser

[PeterA23]

After having RESTARTED my MAC, I had the following problem:
While my Windows 10 VM was running, Youtube videos in any MAC WEB BROWSERS did not play anymore. I shut down the VM and restarted the MAC WEB BROWSER. Then I restarted the VM. From now on, Youtube videos in the MAC WEB BROWSER are playing without problems!
