Those are not difficult to fix. But yes, it is something that we should worry about since Windows updates are breaking a lot of things.
I would suggest using Dual boot and if Windows 10 takes over, let it do that. Once your work from home requirements are over, you can very easily recover your Linux using tools like Boot-repair and so on. There are also tools inside Windows 10, EasyBCD for example, which will allow to recover lost Linux partitions without hassle.
