Problem with menu since update 0.112.4 OS 4.11

I am a new user of HA and since the last update I do not have access to my top menu. I see it during a second and it disappear after.

It is the same on mobile app

Do I need to change something in the configuration ?

Thank you for your help.

I found the problem.
I just remove resources “custom-header” located in Configuration > Lovelace Dashboards >
