Word bullet points

Stefan_Blom I'm using the app:

After checking again, I was mistaken and I do have the "Auto format as you type" tab.

Details of the problem:

When in a list (regular or multi-level list, either bullets, numbers, or any other type of list), I can type an item in the list, and then I hit enter it will create a second entry on the list. But then when the curser is on the second list item, hitting enter or backspace (no matter how many times) does nothing. It will not erase the second list item, or allow me to do anything with the keyboard other than type in a new item (and then continue to add infinite list items). The only way to end the list is to manually click on the list icon or manually change the style to normal. But even when I do that, it keeps the margin/indent set to the same as the list, and backspace will not return the margin to the original left-hand side of the page. I have to manually drag the indent back to the left of the page. 

Example:

   1. Text

   2. [CURSER HERE - BACKSPACE AND ENTER DO NOTHING]

I've tried:

- unchecking/rechecking the "Set left- and first indent with tabs and backspace" (and restarted Word in-between each setting change)

- ran the https://support.microsoft.com/en-us/office/repair-an-office-application-7821d4b6-7c1d-4205-aa0e-a6b40c5bb88b

- uninstalled the entire 365 suite and reinstalled (twice), using the uninstaller tool

This laptop is an HP Envy and was purchased two weeks ago. I don't have this problem on any other device. I also don't have the problem when using the Web version on this laptop, or when running the app in Safe Mode. 

I'm pulling out my hair trying to fix it, it's so frustrating that it's made Word unusable.
