Unable to debug error "ngcc failed to run..."

[Jinnie]

Description:
We have troubles compiling projects which include the Clarity library (https://github.com/vmware/clarity) on Stackblitz with Ivy enabled.

Steps to reproduce:

• Deploy clean Angular project.

• Add these dependencies to package.json:

    "@clr/angular": "^4.0.0",
    "@clr/icons": "^4.0.0",
    "@clr/ui": "^4.0.0",
    "@webcomponents/custom-elements": "^1.0.0",

Live reproduction:
https://stackblitz.com/edit/angular-ivy-issue-repro?file=package.json

Result:
ngcc failed to run on @clr/angular@4.0.9

Expectations:
We are unable to debug the issue based on this error message only. We would appreciate any additional information or logs.

Notes:

• Downloading and building the project locally works.
• It works fine with Ivy off.

Same happens with Taiga UI:
taiga-family/taiga-ui#109

Here's our starter that fails if you enable Ivy (although library itself works fine with Ivy):

Seeing this on a basic Angular 13 setup with NGXS, FullCalendar, etc.

ngcc failed to run on @ngxs/store@3.7.3.

Shouldnt Angular 9+ Stackblitzes have no "Enable Ivy" option and be using Ivy by default? This may simplify the ngcc process (just an idea)
