The movement issue when entering or exiting an instance

I tried to find this issue on the forum, but couldn’t. So, I apologise if this issue has already been raised, and please let me know.

Sometimes, when my character walks out of or into an instance, she runs automatically without any key control, as shown in the following video.

If her destination was safe, this wouldn’t be a problem, but as you know, the island is full of danger, so she usually gets injured or dies.

It looks like she’s chasing the pointer, but I’m not sure how to reproduce this movement. This happens from time to time.

I have also uploaded the required files to the following URL.

It would be much appreciated if you could look into it.
Thank you in advance!
