I was running into the same issue yesterday. Spent a couple hours fully uninstalling and reinstalling, and repeated the process with the alternative download files too. None of this seemed to work, so I took a look at my Windows update and there was an optional one pending. After installing that and restarting my computer I tried running the Minecraft Launcher again. This time instead of erroring out it appeared to recognize there were missing updates (or files and stuff) for the launcher, and fixed them.
The launcher is working fine for me now!
TL;DR: Typical reinstall didn't work, checked and ran any windows update, restarted my computer, launcher updated its missing files and worked.
Can't guarantee that this will work for everyone, but I exhausted every other alternative and this was what worked. Let me what happened for you
P.S the name of the update I installed was: 2020-03 Cumulative Windows Update for Windows 10 Version 1909 for x64-based Systems (KB4541335)
