Cannot log into windows account or restore previous version.

Hello this is the first time I have ever made a forum post so sorry if I post in the wrong place or anything. Basically yesterday after I signed into my windows / microsoft account to log into my pc I accidently pulled out the power cable. I was already logged in and nothing was loading but now it doesn't let me sign in at all. It shows my account and accepts my password, it has the loading symbol and says welcome but nothing happens. I have left it for over an hour but it just doesn't do anything. I have tried restarting in safe mode but it does the same thing. I have tried restoring to a previous version but it gets stuck on initialzing and I have tried resetting my pc but keeping my files but it gets stuck at 68%. I have left it for several hours after it gets to 68% but nothing happens. I am not very pc savey so bare with me, hopefully I have explained clearly so you understand.
