Animation file output issues in VC4.4

Hello. I am a Japanese user.
After updating to VC4.4, the animation file (vcax) may fail to be output, or even if the output is successful, it may not be played. After consulting with the agency, it seems that the output is normal in the VC4.3 environment. Is there anyone who is experiencing the same phenomenon?
