I understand that Cubism 5.3 alpha was not an official release, and I am aware of the precautions stated during its use. However, the transition notice was quite sudden, and all of my recent projects were created using the 5.3 alpha version.
Although I did not use any features exclusive to 5.3 alpha, I am now unable to open these files in version 5.2, which is causing significant disruption to my workflow.
I would like to kindly ask if it would be possible to temporarily regain access to the 5.3 alpha version until the official 5.3 release, or if you could provide a way to open 5.3 alpha files in 5.2 (as I did not use any 5.3-specific features).
I truly appreciate your time and consideration, and I hope for a solution that can minimize the impact on ongoing projects.
Thank you very much.
