Illustrator is not copy and pasting on PC platform

Hi All,

looking for some help. Our company just did a server update and now a large portion of our team is unable to copy and paste within illustrator. Occasionally it will work only seconds later to fail. or when copying text, when pasted the text goes to the default size and style.

Anyone have any ideas on what could be doing this? we've already tried resetting our preferences and restarting the computers.

I should also say initially when we started up the SVG code was checked under preferences so ai was only pasting code. Not sure if this helps or not.

TIA for any help that can be given. You dont realize how often you copy & paste until it doesn't work anymore.
