Publishing works correctly on the Customization Projects List page,
but an error occurs on the Customization Project Detail page.

Hello ​@AndrewZ You can follow this points:
 

Acumatica Support confirmed this fix for .NET Framework 4.8+ compatibility issues:​

  1. Open web.config in your Acumatica site root

  2. In the <appSettings> section, add:

    <add key="aspnet:DisableAppPathModifier" value="false" />

  3. Save the file and retry publishing from the editor

Stale validation files can cause hash mismatches:​

  1. Navigate to your Acumatica site's C:\Windows\TEMP\ and delete old 7764f32b-... folders

  2. Also clear the Customization\[SiteName]Validation\ folder inside your Acumatica instance directory

  3. Restart IIS and retry

Unpublish All, then Republish.

 

I hope this helps.
