Microsoft Office Opening Problem

[Goofy]

I can't open MS office - orany of my files (Excel, Word, Publisher). Nothing happens at all when I click on a file, or the app. My files are all on my pc and not on one drive.
I tried opening them from the Office ap, and it said it had to upload them before I could open them. I clicked where told, and got unable to upload.
Luckily I was able to send the file I need to open to by OH's computer and enter the information.
How can I fix this! It was OK on sunday.

Which version of Office are you using? (2016? 2019? 365? Something else?). Whichever it is, my instinct would be to go through the 'repair' process for that particular software. (I can find the instructions for you if you wish but you'll probably find it simpler just to google 'repair office 2019', or whatever).

The very first thing to try though, if you've not already done so, is the old trick of 'turn it off and turn it on again' with your computer. It's amazing how often that works!

If you're still getting nowhere, try opening your files with different software, with LibreOffice Calc and Writer being worth a try with your Excel and Word files, respectively.

Thank you. Now solved (and I'm going to bury my head in the sand before I thump it to death).
Got a new hub/router and my AV software decided it was 'untrustworthy' and blocked me from opening files.
