Stuck on loading terrain with Optifine

[muink]

Environment:

Client A "Test":

• Minecraft 1.19.2
• Forge 43.1.24
• Optifine HD_U_H9
• BBOutlineReloaded 2.5
• All configurations are default

Client B "OoO":

• Minecraft 1.19.2
• All configurations are default

Server:

• Spigot 1.19.2
• All configurations are default

Description

I created a 1.19.2 Spigot server on my local computer, but when I log into the server with Client A, I get stuck on "loading terrain" page.

So I use Client B to log into the server and find that Client A has Actually already entered the server (has the player entity).

After killing Client A with the /kill Test, Client A enter the server, but the blocks and entities will not be displayed

Using BBO or Optifine alone will not encounter the above problems, is there any solution?
