Is it "nightly build"? Which operating system do you have? FFDec 18.5.0 on Linux > Please provide any additional information below. If the problem is related to a SWF file, attach it here, otherwise we can't help you. The attached playerglobal.swf is an unusual file - it's part of the Ruffle flash emulator, and is compiled using `asc.jar` with `-apiversioning`. It's not run as a normal SWF - instead, Ruffle extracts data from it during load time. Let me know if you need more details about how it's built (it's associated with https://github.com/ruffle-rs/ruffle/pull/12967)
