'Web application freezes due to unknown System 'Task' (Chrome 101.0.4951.54 / Edge 101.0.1210.3)

Since versions Chrome 101.0.4951.54 / Edge 101.0.1210.3 our web application is freezing while clicking around. Performance analysis in both browsers give no indication as to what is actually happening as the browser freezes as the only thing we see is a Task (long running) allocated to 'System' with no nested information as to what is being executed

The Bottum-Up and Call tree show nothing.

I wonder if anyone else is experiencing this or has an indication as to what might be going on. Web app software has not changed.

While to reason is still unclear. We 'fixed' the problem by removing dependency on '@circlon/angular-tree-component' and rewrote our own component.
