I have Excel 2019 on Windows Server 2019 on a virtual server NOT tied to the Internet. Excel does not respond (Not Responding) every 40 seconds. Works for 20 seconds. No Add-ins, not responding if run as an administrator, not responding if run in safe mode. Same not responding if run w/o firewall or antivirus. I told it not to update or look for updates. It does this w/o having an open file. Any ideas what can be done to isolate the cause or correct it?
