OpenLayers webapplication stopped working in IE11

Question

A few years ago we developed an OpenLayers webapplication. Everything worked fine until a few weeks ago. The application stopped working in IE11, became very slow in Edge. No problems with other browsers. When I try to debug (by pressing F12) IE crashes. The application is used by a few hundred users, a lot of them use IE.

The application loads a big WFS-file. During 5 to 10 minutes IE "does not respond". After that period IE is back and alive, and the application works normally. This behaviour started a few weeks ago.

I have made a Q&D testaccount and link: http://62.212.154.154/geluidregister/inloggen?u=test123&w=test123 As soon as you load the page IE will hang for a few minutes. If you press F12 during that period IE will crash. After those "few minutes" you can use IE normally. This behaviour started a few weeks ago. Edge is also 'suffering' but doesn't crash. Other browsers have no problems.

Settings:

Internet Explorer: Version 11.674.15063.0 Update version 11.0.47 (KB4040685)
Installed KB's since september: KB4051613 KB4049179
KB4041676 KB4040724 KB4038788 KB4038806
IE security zone: Protected Mode enabled (translated from Dutch)
As far as I know there is no Emulation mode (at least I didn't change any settings in that area)

Tests/checks:

Delete cookies and browser history - no results
Reset IE setting - no results
Run in 'compatibility mode' - no results
Test in 'no-Addons mode' - no results
Event error after IE crashes (only when I press F12):

Debugging:

I've tried the following (thanks to IECustomizer Rob):

Open blank page
Apply setting

"Always record developer console messages"
Press F12 and apply settings:

"Network recording ON"

"Break on ALL exceptions"
Go to problem website with the dev tool open

But still IE crashes.

Could it be a recent IE/Edge update that's creating this problem?.

Any suggestions?
