The SeedFileTrial randomly assigns ~50% of non-stable clients to read the variations seed from a file instead of prefs. Since the PRE_ test writes the seed to prefs via WriteSeedData(), the main test fails when the trial puts the browser in the seed-file group because the seed file is empty (kUnloadableRegularSeedNotUsed). Force the SeedFileTrial to the Default group so seed loading always reads from prefs where the test seed is stored. Resolves https://github.com/brave/brave-browser/issues/54577
