Facebook main app error

[HaithamDarweash]

I am getting this error from the main app only 

The clone app working fine

The browser woring fine 

I tried to clear all data and reinstall the app but the same issue

I tried to reset all the phone app configuration but not solved 

I tried all the possible solutions i got fron the google search and the YouTube too... Failed

Also the business app 

I need to use it again normally

A friend suggested that you reinstall the application again and log in, and if this procedure does not work, I suggest that you log in from the Google Chrome browser

I did all of that normally
But i need to use the business app and also this with the messenger app

Did you try to do the following steps removing the clone app by disabling the dual messenger feature, then removing the main app and then reinstalling the app again (p.s. clear the app's data before removing the app itself)?

yes i did these steps too, with no luck
