Start with src/Magento/FunctionalTestingFramework/Util/Manifest/DefaultTestManifest.php around lines 68 and 93, as shown in the stack trace. Reproduce the issue with vendor/bin/mftf run:test AdminQuickCheckoutSalesOrderCreateTest --remove and inspect the manifest-generation path. Done means the command creates testManifest.txt and executes without the reported fatal error.
