Bootloop / Rebooting when WiFi is turned on? - LG G5 Questions & Answers

Hi Folks,
3 nights ago for the 2nd time only, I connected to the Internet with WiFi and I noticed some apps were being updated. Somewhere along the way Automatic Updates was reset from Off to Via Wi-Fi only. It stopped on the third.
apps_Packages info is reporting the following 3 apps, in descending Date and Time order, as being updated but they still appear listed in the screen for App Updates which is accessed from the Update Center listed on the screen for About Phone.
LG Account
RemoteCall Service
LG Mobile Switch
My intention was to to look at LG SmartWorld to see what Dark Themes they have to offer before disabling this app. I would like a System Wide theme with Black Text on a Grey or Dark Grey background.
Are themes an inherent feature of Launchers that are automatically applied to all apps?
Not too long afterwards the phone Rebooted and this would happen again after 2 or so minutes each time after I entered my PIN and started checking settings etc.
I turned off WiFi and the rebooting stopped.
I noticed afterwards that less RAM is being used by the System.
Same thing started happening again the following morning when I turned Wi-Fi on again.
Has anyone else had a similar experience?
Have I possibly disabled something that is required for WiFi to function correctly or for apps to be able to properly communicate with the Wi-Fi processes?
I had previously used the Force stop button for apps such as Gallery, Weather, My Places, Email, Exchange, QuickMemo+ etc.
There does not appear to be a Software Update to Oreo 8.0 available but the following apps are listed as having updates available. Do they need to be updated first in order for the system to "properly" check for a Software Update?
Email
Home & app drawer
LG Account
LG Keyboard
LG Mobile Switch
QuickMemo+
RemoteCall Service
Weather
What I would like to achieve is to have everything disabled as much as possible before removing the SIM Chip from my old phone and installing it into this one.
The following Apps, I want disabled, but keep appearing in the lists of Running Services and Cached Processes even after I have used the Force stop button and after every Reboot.
Email
FmService (Can this be replaced by a Third Part app?)
Gallery
My Places
QuickMemo+
RemoteCall Service
Weather
Weather Service
I want the following disabled also.
Exchange
LG Account
LG Backup
LG Health
LG Keyboard (after installing AnySoftKeyboard)
Is the only way to ensure this, without loading another ROM, to use ADB (Android Debug Bridge) and uninstall the Apps? I am using MX Linux.
I have seen various Debloat lists on this forum and there is some useful information provided via the following page.

My phone is using com.android.captiveportallogin - Version 7.0 (24). The Disable button is disabled for this app.
Which apps should not be uninstalled with the approach I am taking to mitigate privacy concerns?
For example, is it safe to uninstall the standard Contacts (com.android.contacts) and Contacts Storage (com.android.providers.contacts) apps or are they required by some of the Third Party apps, for Contacts, in order to function properly?
Can the Messaging (com.android.mms) and Phone (Call services - com.android.phone) apps be uninstalled and replaced by Third Party apps such as QKSMS and Simple Dialer?
My current Home Screen (Home & app drawer - com.lge.launcher2) had a Time and Date and Weather widget but, even though I have removed it, the Weather apps still appear in the lists for Running Services and Cached Processes after every Reboot.
Checking the Uses permissions list of apps_Packages info reveals that the Home & app drawer has references to Email, FormManager and Weather.
Could the Email, FormManager and Weather apps be prevented being used by using a different Launcher? Which Launcher?

Which Weather apps are recommended as a replacement?
I also want to prevent all the Offers (Advertisements) I keep receiving from my current Service Provider via SMS.
Can this be done using the SIM Toolkit?
Is the SIM Toolkit an app that should not be uninstalled?
Should I do a Factory Reset and start again? If so, will I need to disable, again, all the Gulag (Google) apps that I previously disabled with the Disable button?
Which of the methods on the following page is the best to use?
How to hard reset an LG G5
According to the following page, "If a pattern, PIN, etc. is or has ever been set up on the device, Google account sign-in is required during initial setup."
I am using a PIN but a Google Account has never been configured for the phone.

Here's how to factory / hard reset your LG G5 if the screen freezes or call, app, audio or sync issues occur and the device won't start up.

If I do a Factory Reset should I attempt to have the App Updates done before starting to disable any other apps?
What other information could I provide that would help to pinpoint the cause of this problem?
Thanks, M.
