Error when using Spire.XLS on deployed environment

[vict0rcarvalh0btg]

I've done a task using Spire.XLS on .NET 8 to create a new Excel file recently, locally on Windows it worked perfectly, when deploying to production(Linux EC2) I start having errors involving the Spire use. Can anyone help me?

The error occurs when passing this row: Workbook workbook = new Workbook();
The errors that occur are the following:

fail: Finest.Api.Business.Implementations.DigitalReport.DigitalReportBO[0]
Error on ExportCompleteDigitalReportToExcel: The type initializer for 'Spire.Xls.Core.Spreadsheet.XlsPageSetupBase' threw an exception.

I already tried installing some graphics via Dockerfile:
FROM base AS final
RUN apt-get update \
&& apt-get install -y --allow-unauthenticated \
libc6-dev \
libgdiplus \
libx11-dev \
&& rm -rf /var/lib/apt/lists/*
WORKDIR /app

I tried to use Spire DLL reference instead of using the NuGet package but nothing works.
