I am unable to launch Unity 2019.4.26f1 (64-bit) because of the titular error. I have tried returning, and getting another free license through Unity Hub. I have tried checking what it's binding to via the editor logs, where it is stated. The entire string matches, up until an additional 8 characters at the end which is not in the value it seems to have for my machine. It seems like most people have issues with licensing due to a binding key 5 mismatch of the MAC address, but I can't find info for how to resolve a binding 4 mismatch. I have included the log file for Editor, and licensing. I have also tried a workaround I found online to do a manual activation of a free license, but after editing the alf file to match what it seems to want for binding 4, uploading it, downloading the ulf file, it then won't activate in Unity Hub.
