With Memory integrity protection, kernel memory pages are only made executable after passing code integrity checks inside the secure runtime environment, and executable pages themselves are never writable. This is an enhancement to intrusion prevention capabilities in Windows Defender Exploit Guard.
You may create a new user profile and check if it works fine on the new profile. Refer Create a local user or administrator account in Windows 10 to know how to create a new user profile.
Hope it helps.
