RT-AX88U UI crashing when looking at network maps or AiMesh

[MatynK]

Just this afternoon, when I login to the web interface on my RT-AX88U I can get it to crash in a couple of ways.
1st if I click the "View List" on the network map page, it will display an empty list, then my browser says the page is slow. After a few seconds more it displays the client list, then logs me out.
2nd if I click the AiMesh tab, it goes to the screen, shows my two routers with 0 clients, then after a few second more it logs me out.
This is running Firmware 3.0.0.4.386_42095 which up to now has been running fine for 4 or 5 days without issue.
I have tried rebooting the main router and nodes, both soft and hard reboots, cycling the power.

I am not an expert in this, but looking at the last entries in the log file, I am guessing that the HTTP service is crashing and restarting each time I try this.

Anyone have any ideas ?

This is the log file and its repeated each time I try and view the client list.

So I have had a major play, dropped back to the previous version of the firmware - still broken.
Upgrades back to the latest version - still broken.

Factory reset and manually reconfigure everything from scratch with the previous settings - fixed.

The only thing I can think that has caused this is I "renamed" the devices to give meaningful names.
Some of the devices I also used custom icons instead of the stock ones available.

So one of these two things must be crashing the HTTP/S process once they have been changed for some reason.

I will re-enter all the machine names so they are meaningful again, but I will skip putting the custom icons, because my money is on that crashing the service.
