As this is tagged with "bootstrap-4" I'm assuming it's related to this bug in Bootstrap 4.1.0 where all collapsibles were unclosable in IE11.

More specifically, it was line 334 in Bootstraps js/src/collapse.js that was causing the problem. It was changed from
...typeof config === 'object' && config to
...typeof config === 'object' && config ? config : {}

Quoting this page: "If config is not an object, this is false. In IE, Object.keys(false) results in an error, while modern browsers return []"

The bug was fixed in subsequent versions. I had the same problem in a project recently and updating Bootstrap to version 4.1.1 fixed the problem.
(Update package.json with "bootstrap": "v4.1.1"(or later) and run npm install.)

TL;DR: It's a Bootstrap bug. Update Bootstrap to version 4.1.1 or later.
