Protocol settings open along with Chrome

As of recent, every time I open chrome, this window pops up: The default application for protocols window annoyingly pops up. How do I fix this?

Edit: I've tried deleting the cache, but this window still pops up. I've also tried setting the default browser to another browser nd setting it back to Chrome. This issue still persists. What do I do?

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.
