Not sure if this is only happening to me but if I try to enter a portal while my character is "breathing" or during and invincibility frame the portal freezes the game client and eventually has to be manually force quite due to the application "not responding". I have tested this multiple times and I CAN move through portals fine if my character is NOT in the process of breathing after skill use, Or after invincibility frames stop After being hit by a monster. Thanks
If you are still having this problem could you try changing compatibility on the client, it seems to have worked for a few others having something similar to what you describe. https://royals.ms/forum/threads/portals-freezing-the-game.87623/#post-461407
