Gitlab CI .NET6 docker build issue

I am working on a GitLab CI/CD project to build a NET6 application into a docker image, which is pushed to AWS ECR. My issue is manifested in the continuous failure of 'COPY . .' or any other command after 'restore' of my targeted project.

Repo structure:

repo root
-   projectFolder
        - projectAPI
            -   projectAPI.csproj
            -   DockerFile
        - nuget.config
        - referencedClassLibrary1
        - referencedClassLibrary2
        - .sln
-   gitlab-ci.yml
-   package.json

Dockerfile:

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build-env

EXPOSE 80

WORKDIR /app

ARG Nuget_CustomFeedUserName
ARG Nuget_CustomFeedPassword

COPY "TT.CS/TT.CS.API/nuget.config" ""
COPY "TT.CS/TT.CS.DAL/TT.CS.DAL.csproj" "TT.CS.DAL/"
COPY "TT.CS/TT.CS.BLL/TT.CS.BLL.csproj" "TT.CS.BLL/"
COPY "TT.CS/TT.CS.API/TT.CS.ConfigAPI.csproj" "TT.CS.API/"

RUN ls -al
RUN sed -i "s|</configuration>|<packageSourceCredentials><aws><add key=\"Username\" value=\"${Nuget_CustomFeedUserName}\" /><add key=\"ClearTextPassword\" value=\"${Nuget_CustomFeedPassword}\" /></aws></packageSourceCredentials></configuration>|" /app/nuget.config

RUN dotnet restore --configfile "/app/nuget.config" "TT.CS.API/TT.CS.ConfigAPI.csproj"

COPY . .

WORKDIR "/app/TT.CS.API"

RUN dotnet publish --no-restore -c Release -o /app/out "TT.CS.ConfigAPI.csproj"
FROM mcr.microsoft.com/dotnet/aspnet:6.0
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "TT.CS.ConfigAPI.dll"]

Outcome:

#17 3.891   Restored /app/TT.CS.BLL/TT.CS.BLL.csproj (in 1.58 sec).

I've created a solution with a single folder sln/csproj without referencing the same solution projects, which works as expected but I'm still having issues with more complex solutions that combine multiple referenced projects with public and private nuget repos. Does anyone see some obvious mistake? Thanks
