Not a solution but more of a suggestion here as to what may be the cause: As you may know, Windows 10 keeps updating whether you like it or not. Windows 10 updates can cause booting issues, especially if the update involves updating your Windows Build. There is no way of knowing whether a Windows 10 update will break your dual boot setup with Linux and hence, why I suggest to disable Windows 10 updates altogether. There is a way to stop Windows 10 updates completely but you will need to do disable it via Task scheduler and some other ways.

Personally, I would only run a Windows and Linux Dual boot if and only if Windows OS update is disabled. The beauty of Linux is that it never updates by itself unless you issue a command to do so in the terminal, unlike Window and thus, prevents this kind of issue from happening. You may try to boot one day only to find out you can't because it causes boot issues (either it messes with the GRUB2 boot loader or something else - You can google cases of Windows update causing issues on Linux and Windows dual boot to find out more ).
On a clean install, I would update Windows 10 first to the latest version to be able to get the latest security updates and then make sure to disable Windows 10 updates completely. Afterwards, thats when I install Linux. I don't bother updating Windows 10 afterwards, only until my next reformat. I have setup my dual boot Windows 10 & Linux Laptop this way and for the past 2 years, have no problem booting. I only update my Linux distro instead.
