IDE crash at module jscript9.dll showing the welcome page and function's hints

Question

I have Delphi XE7 installed on a Windows Server 2012 R2 (64 bit).

One week ago, it started crashing on startup, while displaying the welcome page with the following error message:

I didn't understood the real cause of the problem, I've searched for jscript9.dll and found that it could have been something related to the welcome page, so I've disabled the WelcomePage from the registry and temporarly avoided the problem.

Today it has started to crash again, with a very similar error, on displaying the functions hint.

Both errors also happen on a new project, created running the ide with the -r parameter:

bds.exe -r foo

Using Process Monitor, it seems that something is going wrong with internet explorer (?):

I knew that Welcome Page is being basically displayed within a TWebBrowser component that is just a wrapper for Internet Explorer. But I never ever thought that Help insight is even remotely connected to Internet Explorer. If that is true then there will be lots of any Delphi users when Help systems stops working just because Microsoft decided to remove IE entirely. — SilverWarior, Jul 14 '21 at 14:13
@Olivier: No, the pc has not been updated for long time (And I'm suspecting that the problem is related to this, I will try to update the OS later) — Fabrizio, Jul 14 '21 at 14:25
@SilverWarior: I had some problems with the hints in past, using Delphi 2007, and I know that the hint is basically an HTML page (see [this question](https://stackoverflow.com/questions/51472972/delphi-2007-ide-hints-displayed-as-html-text)) — Fabrizio, Jul 14 '21 at 14:30
@Olivier: Updating Windows completely resolved the problem. I also have enabled the welcome page again. Thanks for the hint — Fabrizio, Aug 16 '21 at 06:44

I found a way to avoid the IDE crash, but I'm still looking for a real solution...

In Tools -> Options -> Editor Options -> Code Insight:

I've disabled the "Tooltip help insight" checkbox and the crash has been avoided (But obviously, I have no tooltip now....)
