Build error using parallel test feature and text fixture name filter contains double quote

We are using TeamCity version 2025.11.1 (build 207998) and are using the parallel tests feature. We have a couple of TestFixtures that are using parameters, specifically a string parameter. When this TextFixture filter gets added to the runSettings file it escapes the paratheses and the double quotes. When the double quotes are escaped it causes an exception to be thrown:

If the double quotes are not escaped then no exception is thrown. Are the double quotes in the runSettings file supposed to be escaped or not? What generates the contents of the runSettings file, is it TeamCity or one of the Test Adapters that does that?

Thanks,
