I cannot open links in Chrome on my iPhone 13 running 15.5 ios. Chrome is selected as my default browser. Help.

Sorry, I don't have Chrome installed any longer to follow along.

Did you try Chrome Support? Plenty of articles here:

Worth trying if you have not already done so.

On the iPhone, go to Settings/Apps/Default Apps and make sure the default Web browser says Google Chrome.

Click on the link right below it that says "Choose default apps by file type".

Scroll down to . URL and make sure the app out to the side says "Internet Browser" and not Google Chrome.

Try Settings > Chrome > Default Browser > Chrome

Tap on the link right below that says "Choose default apps by file type".

Scroll down to . URL and make sure the app out to the side says "Internet Browser" and not Google Chrome.
