I have a vision client that is taking 10+ minutes to load since upgrading to ignition 8.3.1 (From 8.1).

The issue appears to be caused by the JxBrowser failing to initialise causing the client to hang until an exception is thrown. See logs below.

In 8.1 I had a similar issue which was fixed by disabling the Web Browser Module which would stop the JxBrowser from initialising in the first place. However in 8.3.1 I've not found a way to stop JxBrowser from initialising.  
I havent got any Web Browser components in the project, and I've tried disabling the reporting module.

This issue is only present on one HMI I have for dev purposes; the same client opens quickly on my local machine.  
Problem machine: Windows 10 IoT Enterprise LTSC 21H2, Intel Celeron N2930, 4 GB RAM, Sentinel Agent + Sentinel Firewall enabled, Windows Defender and Windows Firewall disabled.

I suspect this may ultimately be an antivirus / endpoint protection issue on this particular HMI, but if there’s any supported way to get around the JxBrowser initialisation within Ignition 8.3, that would be my preferred solution.

The web browser component is now part of core Vision... you'll have to solve this IT problem unfortunately.

That said, we have a (very) old ticket to improve the way Vision loads the web browser component to do this in the background, so at least the rest of your Vision application would still be useful even if this is taking 10+ minutes in the background.

I've revived that ticket with an escalated priority, since the move to embed the web browser component will probably make it more of an issue.
