How to revert to win 10?

My computer keeps on trying to go to 25H2, but blue screens on restart. I tried to update to 25H2 in FLYOOBE, but it does the same thing. Every time I restart I have to use a USB key and revert to a prior good date. PITA.

I just want to go back to win 10 for now. Tried in settings but it says win 10 files not available.

Any ideas?

Thanks,
John

The report names FLYOOBE, Windows 11 25H2, and a failed restart, but it does not identify a file, test, or entry point to inspect. Start by determining whether this behavior is within FLYOOBE's scope and how the upgrade path is handled; the issue needs a reproducible failure and a defined expected result before completion can be assessed.
