System.InvalidOperationException: Operations that change non-concurrent collections must have exclusive access
I have a problem with the current version in a Linux container using 2024.1.30 and 18.0.24.305 version of reporting. I only get this when I'm attempting to produce multiple reports at the same time.  It's the same issue regardless of whether it's running as a hosted web service or if I'm running as a server based blazor app.

DockerBlazorApp Error: 0 : An error has occurred while rendering the report: System.InvalidOperationException: Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state. The collection's state is no longer correct.

Hello John,

We have fixed the issue and will release it with the new version 2024 Q2 scheduled for release on May 15th, 2024.

Along with the fix of the discussed problem, we will provide performance improvements for the Skia graphics engine.

Regards,
Todor
