I am running Hyper V server 2019 and running 2 windows 10 VM (only OS running) and 1 Windows server essentials 2019. It worked fine for 6 months just running basic AD tasks. a management software was installed and we had issues since.

The 2 windows 10 VM can't start up. An error occurred while attempting to start the selected virtual machines 'Windows 10 VM' failed to change state

 

When I starte the windows server 2019 essentials a Paused-Critical shows on STATE and Status is 'Disk(s) encountered critical IO errors. there's plenty of available storage space in the VM

 

 

Can anyone help?

 

thank you
