Is there any way to downgrade DeepAR Studio?

Currently, I am experiencing this issue A very serious issue has occurred. I urgently request a prompt response. "initializeOffscreen dosent work with new version of deepAR", and it hasn’t been fixed for a long time. I need to create effects that can work well on version 5.4.1. With the latest version of DeepAR Studio, the exported effects don’t work. This is a very urgent issue for me.

Could you check with the latest version of the SDK which should solve that issue?
