Windows 10: Stepwise kind of "automated" downgrade of my Win 10 64-bit Pro via Win Home and Win...

A couple of weeks ago I bought a new Computer to run my Microsoft Flight Sim Programs on the basis of Win 10 Pro 64bit. Recently I got stuck during an update of MSFS2020 by means of a blue screen "Problem" with an immediate shutdow and restart. Thererafter I found my Computer running with Win Home and the MSFS 2020 always gets stuck with "looking for updates". But I still could run FSX. Again 3 days later I got another "restart" and another version of windows : "Win Enterprise" with a warning that my computer is no longer running in a safe mode. So I used my Key to get back to my originally installed version: Win 10 Pro 64bit. But it said that the key is not valid. What options do I have? Can somebody give a hint?
