Error when distributing to App Store Connect

Everything has been working fine and our app is in the App Store but when I try and push an update I get the following error:

"The archive did not include a dSYM for the OneSignalV5Plugin.framework with the UUIDs [{UUID_HERE}]. Ensure that the archive's dSYM folder includes a DWARF file for OneSignalV5Plugin.framework with the expected UUIDs."

The only thing I changed in the app was the splash screen image.
