numbers file format 'invalid' osx 15.0.1

I have a numbers document that fails to open - relocated an older version of the file through time machine opened fine spent ages working on it, two weeks later does the same thing again. I even saved it in two location neither of which work now.

I also have a secure folder (bank details) which has started to not open and have to do the same thing use time machine to find an older version.

it is to do with the drive optimisation in OSX never had a problem before. OSX 15

it is very annoying for something that has been rock solid for 15 + years.

Looked around there are about 20 other threads with this same problem, from the last 4 years. seems some bug in the software that corrupts the file, to do with reverting to previous version. Should be fixed but isnt, going to look for a different spreadsheet now shame used numbers loads but cannot risk losing all my data like this again.

Everyone's experience varies, but I have used Numbers for a long time and have never run into a problem with file corruption.

I save my Numbers documents on iCloud Drive and/or on the internal drive. Where do you save yours?

Are you using an old version of Numbers on the Mac and syncing with Numbers on an iPad or iPad?
