Adobe Animate CC 2020: Issue with Macbook Pro

I have a Macbook Pro 16", Core i9, 16GB ram, GPU: AMD 5500 pro, 4GB VRAM. I tried several times to import a simple vector (about 40 Mb)  to adobe animate cc (latest version), and it either crashes or gets freeze for a long time, and I have to force quit Adobe animate. Since there is no preference setting for adobe animate; unlike photoshop or premiere, what should I do?

Thanks in advance.
