Why is the casting of World of Warcraft nostalgic costume team stuck?

The casting of the World of Warcraft nostalgic costume team is stuck because of the plug-in problem. Just close the "casting progress".

Tools/raw materials:

Dell G3

Windows 10

World of Warcraft 3.2

1. We were playing a game and found the Bigfoot icon near the map.

2. Then we click on the icon of bigfoot.

3. Click to enter bigfoot's page.

4. On the third page of Bigfoot plug-in, find the icon of the avatar.

5. After finding the avatar icon, click the avatar icon.

6. After clicking on the avatar, we can find the information of teammates on the avatar page, without checking the casting progress of teammates.
