Cannot open sharepoint files in app depending on date
I have switched to a new laptop. Running Windows 10. Installed everything I needed. For Office I used the installer from Microsoft 365.
Now, when I try to open a sharepoint file in app mode, I get an error message very often. BUT: This happens only to files that were uploaded into sharepoint (or modified) in a certain date range (which I can not identify). Happens for all my sharepoint sites.
Very old files: No problem!
Save a new file to any sharepoint folder: No problem!
Download a file and resave under a different name: No problem, can be opened in app mode from then on.
Open file in web mode: No problem!
As a walkaround I could of course download all the problem files and resave them. But that would mean many, many hours of work.
All I noticed during my investigation is that the new laptop has a slightly newer office version than the old one that still works perfectly.
Anybody have an idea how to solve this?
Thanks in advance for any hints you could give me.

This is my soul opinion, if in your old computer works, should work on the new one, we agree on it.
The ONLY reason I see it, don't forget to read the Microsoft 365 Roadmaps in your subscription as ADMIN, is both computers have different policies.
Make sense to you?
No, these are all files that I created myself over a long period of time.
I uploaded them into SharePoint libraries to make sure I can access them from anywhere.
No problem with my old laptop...What type of files?
One think in the equation is tou have a new laptop and a new Office Version. Laptops are managed by your company, and a new version of Office might change from 32bits to 64 or the opposite.
So the only thing I see it is you have macros pointing for 32 or 64 that are incompatible or you have new restrictions on your new laptop.
