Here’s how to fix the ftdibus.sys error blocking Memory Integrity:

1. Update the FTDI driver from the official FTDI website.

2. In Device Manager, find the USB device using the FTDI chip and update its driver.

3. If updating doesn’t work, disable the device in Device Manager, turn on Memory Integrity, then re-enable the device.

4. Restart the PC after updates.
