Hi @Anonymous

Is there anything has been changed before the issue occurs? You could try to use powershell to activate Publishing Feature.

Site collection features:

#Variables  
$SiteURL="your site collection url"  
$FeatureName = "PublishingSite"  
   
#Check if publishing feature is already activated in the site collection  
$Feature = Get-SPFeature -site $siteURL | Where-object {$_.DisplayName -eq $FeatureName}  
if($Feature -eq $null)  
{      
    #Enable the Publishing feature   
    Enable-SPFeature -Identity $FeatureName -url $SiteURL -Confirm:$False  
      
    Write-host "Publishing Feature Activated on $($SiteURL)" -ForegroundColor Green      
}  
else  
{  
    Write-host "Publishing Feature is already Active on $($SiteURL)" -ForegroundColor Red  
}  

Site features:

#Variables  
$WebURL="http://sp/sites/caseytest"  
$FeatureName = "PublishingWeb"  
   
#Check if publishing feature is already activated in the site   
$Feature = Get-SPFeature -Web $WebURL | Where-object {$_.DisplayName -eq $FeatureName}  
if($Feature -eq $null)  
{      
    #Enable the Publishing feature   
    Enable-SPFeature -Identity $FeatureName -url $WebURL -Confirm:$False  
      
    Write-host "Publishing Feature Activated on $($WebURL)" -ForegroundColor Green      
}  
else  
{  
    Write-host "Publishing Feature is already Active on $($WebURL)" -ForegroundColor Red  
}  

Per your ULS log, have you tried to check permission for "_DeviceChannelMappings.aspx"? You could use SharePoint Designer 2013 to check the permission.
