I have been unable to launch Excel for MacOS from "365" on Sequoia ever since my install of Sequoia in the fall. Bounces twice and then nothing, Application Not Responding, must Force Quit. Has happened all the way from 15.1 to 15.3.1.
This is a known issue, some sites say it's a font issue, but I checked all fonts for problems and deactivated ALL user fonts as well, and that only allowed me to open a file by double clicking the file in the Finder (not by trying to open Excel first). As soon as I tried to click on a cell, spinning beachball. Now it won't launch at all again. Safe mode allowed me to launch a blank sheet. Open a file. Open 3 files at once. Try to edit the file and beach ball.
I have been using Excel for Mac since 1992 and Windows since 1990 and I am no stranger to troubleshooting both over the last 30+ years. But I can't even figure out where, if anywhere, Excel is saving caches or prefs or support files to trash.
I trashed the App itself and had MS reinstall it. That made no difference.
One "solution" is to reinstall my OS, but that's a bridge to far to fix MS's issues whenever. There is obviously a corruption somewhere that Excel just can't ignore while every other app installed on my system doesn't care about, including Word, Powerpoint, etc.
