What Causes Rtu53cx22x64.sys on Windows 11?

The Rtu53cx22x64.sys file is part of the Realtek USB GBE Family Controller package. Its main responsibility is managing USB-based Ethernet adapters. But when it becomes corrupted, outdated, or incompatible with the system, it can trigger crashes and BSODs. Several factors can cause this blue screen error. The most common reasons include:

  • Corruption in the Realtek audio driver
  • Conflicts between newly updated drivers and Windows 11 or Windows 10
  • Compatibility problems between older hardware and new drivers

The most likely cause of this BSOD error is the Realtek USB GBE Family Controller drivers and the Realtek audio drivers. So you'll probably have to roll back to an older driver or clean install the current one.

  • Open the Device Manager by pressing Win+X and selecting Device Manager.
  • Locate your Realtek network driver, right-click, and select Properties.
  • In the Driver tab, choose Roll Back Driver.
  • Repeat the same process for the Realtek audio driver under the Audio inputs and outputs section.

If the rollback option is unavailable, you may need to manually uninstall and reinstall the older driver.

Uninstall the network driver

A less likely possibility is that it is an external Ethernet adapter incompatibility with newer Realtek drivers that can cause blue screens. So uninstall the device and see what happens. If the problem goes away, you can reinstall the driver.

  • Open Device Manager and expand Network adapters.
  • Right-click the Realtek network driver and select Uninstall device.
  • Check the box Delete the driver software for this device and confirm.
  • Restart your computer.

Uninstall the audio driver

A corrupted Realtek audio driver can also be the source of the problem.

  • Open Device Manager and expand Sound, video, and game controllers.
  • Right-click the Realtek audio driver and select Uninstall device.
  • Select Delete the driver software for this device and confirm.
  • Restart your PC.

If the blue screen disappears after uninstalling, download the correct version of the audio driver from the official Realtek or PC manufacturer’s website and reinstall it.

Disable automatic driver updates (Temporarily)

Sometimes Windows automatically reinstalls problematic drivers. You can prevent this temporarily.

  • Press Win+R, type gpedit.msc, and press Enter.
  • Navigate to: Computer Configuration > Administrative Templates > Windows Components > Windows Update > Manage updates offered from Windows Update.
  • Double-click do not include drivers with Windows Updates.
  • Select Enabled and save the changes.
  • Restart your system.

Adjust power settings (Not likely, but worth a shot)

Power management settings can sometimes interfere with Realtek drivers.

  • Open the Control Panel and go to Power Options.
  • Select Choose what closing the lid does from the left panel.
  • When I close the lid, set both On battery and Plugged in to Do nothing.
  • Save the changes.
