Issues with mirror reflections

Rendering

There is flickering shadow bubbles and texture defects only in my mirrors reflections, while the rest of the scene seems ok. All the resolution changes I make in the project settings change the entire scene except the reflections of the mirror.
This problem seems to be affecting a lot of people

I’m using the default settings of the architecture scene.
UE 5.5 version
Geforce RTX 2060 super
Global Illumination: Lumen
Reflections: Lumen

Things I’ve already try to fix this but didn’t work:

Try using the previous version UE (5.4)

Increase the resolution to Cinematic

Try using planar reflections

Update my video card driver

Reinstall Unreal Engine

Create a new project

Try with a different type of light

Fix the normals of the reflected objects and the mirror itself

Use the default UE shapes like a cube for the entire scene

Increase the screen percentage to 100% or more

Change the materials of the objects and the mirror

In GI, increase the “Final Gather Quality”

Increase the Lumen Reflections quality

Select the “High Quality Translucency Reflections”

Increase the Sample Per Pixel of the light

Increase the reflection bounces

Check “Hit Lighting for Reflections”
