Hello! I'm using version 13.3.1 and I run my umbraco sites via a publish through devops and then into Octopus. Usually ones it's built, the websites are then visible and work as expected. This is my first Umbraco 13 site and I'm receiving errors when trying to view the pages, though the backoffice seems to work perfectly.

Has anyone experienced this before? I tried emptying out /Views/Home.cshtml to see if this made a difference but nothing changes. Here is my csproj if this is helpful for seeing where I'm going wrong:

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <TypeScriptCompileBlocked>true</TypeScriptCompileBlocked>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Our.Umbraco.ConditionalDisplayers" Version="3.4.0" />
    <PackageReference Include="Umbraco.Cms" Version="13.3.1" />
  </ItemGroup>

  <ItemGroup>
    <!-- Opt-in to app-local ICU to ensure consistent globalization APIs across different platforms -->
    <PackageReference Include="Microsoft.ICU.ICU4C.Runtime" Version="72.1.0.3" />
    <RuntimeHostConfigurationOption Include="System.Globalization.AppLocalIcu" Value="72.1.0.3" Condition="$(RuntimeIdentifier.StartsWith('linux')) or $(RuntimeIdentifier.StartsWith('win')) or ('$(RuntimeIdentifier)' == '' and !$([MSBuild]::IsOSPlatform('osx')))" />
  </ItemGroup>

  <PropertyGroup>
    <!-- Razor files are needed for the backoffice to work correctly -->
    <CopyRazorGenerateFilesToPublishDirectory>true</CopyRazorGenerateFilesToPublishDirectory>
  </PropertyGroup>

  <PropertyGroup>
    <!-- Remove RazorCompileOnBuild and RazorCompileOnPublish when not using ModelsMode InMemoryAuto -->
    <RazorCompileOnBuild>false</RazorCompileOnBuild>
    <RazorCompileOnPublish>false</RazorCompileOnPublish>
  </PropertyGroup>

</Project>

Any help would be fantastic!
