As for many other Lottie plug-in stopped working on the Windows 7 AE 2019 (16.1), but still was for me on the Windows 10 AE 2023 (23.3) and I thought Lottie stopped support of old versions of AE and Windows 7.
However, your version works fine for me on Windows 7. Thank you very very much!
Can you share more info with the community about what we should do if the same happens again?
