4.0.2 Error - Exception in thread Thread-30 (__update_plugin) | TypeError: 'NoneType' object is not iterable

[AnthonyBe]

Describe the bug
Was running 3.4.0.5 and upgraded to 4.0.2
Running this on Windows Server 2016 with python 3.12
On start-up of Glances in web-server mode I get the following error.
Glances continues to start-up and run without issue.

@AnthonyBe
Could you run glances with these arguments and provide the logs?
Add these after the current command that you use to run glances.

--disable-plugin alert,processlist,wifi,fs,network,diskio,cpu,load,mem,memswap,quicklook,gpu,ip,raid,containers,folders,percpu,uptime,amps,processcount,core,cloud,help,now,ports,system -d

I think this is the same issue as in #2763

[RazCrimson]

@AnthonyBe
Please upgrade to 4.0.3. That should fix the issue

Upgraded from 4.0.2 to 4.0.4 this morning and it has resolved the issue! Thanks!
