I have the same issue now after Xcode 26.4 has been released and changed these entitlements. My apps have been rejected with the following: Entitlement "com.apple.security.hardened-process.enhanced-security-version-string" value must be boolean and true. Entitlement "com.apple.security.hardened-process.platform-restrictions-string" value must be boolean and true. It seems to be the same problem where the App Review automated system hasn't been updated to accept the new entitlements even though Xcode 26.4 has been out for more than a week now. I've raised FB22387339 for this.
