Protocol settings open along with Chrome

I would try launching chrome without any plugins or extensions. This is from an old link, but I tested quick and it works. You need to close Chrome completely first.

--disable-extensions Disable extensions.

--disable-plugins Prevent plugins from running

You should check if in PC Settings / Apps / Default apps :

1. Chrome should be the default Web browser
2. Click on "Choose default apps by protocol" and check if Chrome is set as handler for the protocols of FTP, HTTP, HTTPS.
3. Click on "Choose default apps by file type" (very slow to load) check if Chrome is set as handler for .htm and .html

I have confronted this issue one time before but after I set default value for those settings, it never shows up again. I would recommend trying the same thing.
