I experience the same issue in my styles.

EDIT: Upon further inspection, it turned out to be a real CSS error, albeit very hard to spot. In the Blazor server-side exported output, there was a random dot:

.class .{ }

These were bundled component-scoped styles in a single file. The error syntax indicating the line that triggered the error was incorrect. However, I managed to identify the issue manually.
