@Roxy I believe the shift +F10 works to access command prompt only when booting from Windows installation media?
The way I see it, you have very few options.
If you are unable to use recovery environment AT ALL, it indicates WINRE is corrupted in some way so this option won't work. If only accessing command prompt is what is not working and you can get into recovery's other functions , you can attempt a
system reset and remove everything but all your data will be lost. If you have bitlocker/device encryption turned on you may be required to provide your recovery key. Doing a "reset and keep my files" WILL NOT work in this case.
You can do a clean install using Windows installation usb drive. This would be my preference.
Before a reset and remove everything or clean install, I would reset the TPM from within UEFI bios. .
If you have a system image, you can restore it to see if it gets you back into a working state. (but it may not if its the TPM that's at fault) However,
depending on what application you used to create the image, you may can recover your personal files by mounting the image after Windows is back up and running. Again, you may be required to provide a BL/device encryption key.
