There could be any of (at least) three reasons for this in likely order of probability:
1/
There is a trojan that is corrupting memory. Scan using Anti-Malwarebytes.
2/
There is a memory conflict with a driver or something that has become located in an area that IE wants to access. What new device or device driver has been added to the system or Windows update?
3/
RAM is misbehaving. Perform a memory check.
That's what comes to my mind first. Other wisdoms may be offered.
