I suspect you are going to need to do a system refresh but first I would try a system file check to at least find out what the problems are

Please run a system file check (SFC)
All instructions are in our Wiki article below...
Should you have any questions please ask us.

System file check (SFC) Scan and Repair System Files

do you remember if there is any changes before this issue happen?

did you able go to safemode?

do you have any user account at this PC, try to login with another user account, if you don't have try to create using command prompt

net user username password /ADD

example

net user Jane h3rDy4 /ADD

if you are connected to specific domain, try to login without it

check also at Software restriction policies or app locker

Start - run - gpedit.msc - check: Software restriction policies or Applocker

Or check this link and applied troubleshooting

I suggest try first that iCals command

cd /d c:\
icacls * /T /Q /C /RESET

good luck
