What changed on your computers in the last week?
Use Windows Restore to change the computer back to where it was when it worked. I hope you have Restore activated.
Once you get back to where you were, start adding the updates one by one until it breaks again.
I looked and W10 was last updated over a month ago. Check you audio card to see if it as been updated recently. Also check on IPhone updates.
Did you guys check on your Windows settings for audio? It may have changed accidentially.
By the way, clean out your temp files for Wave Editor (and the rest of your computer). Clean them all but you can see what folders are use in Wave Editor preferences.
