Local church Facebook page crashes my PC

This is a weird one and I can't even think where to start looking for cure, so hope someone can help.
Both my wife's and my PC are functioning without problems, Hers is running on Windows 10, mine on Windows 11. Both fully updated.
I can access any Facebook group without problems. My wife's PC can access every Facebook group bar facebook.com/stbeespriory. When she access that, before she does anything else, her PC appears to re-boot and spends about a minute or more accessing the hard disk before eventually re-starting. This only happens with this one Facebook group. It doesn't happen on my PC if I access the same page.
So the problem seems to be with her PC and that group only.
Facebook is not something we use or particularly like so we only use out of necessity because it is useful as a source of village information. So while I am PC literate, I am illiterate when it comes to Facebook.
I hope someone can make sense of what to me seems a weird problem - why only one Facebook group on one specific otherwise healthy PC?

Delete Temporary files.

What happens when a different web browser is used?

Does computer display BSOD error when it reboots?

Make sure to install the latest version of graphics and network cards drivers.

Thanks for suggestions, but I'm afraid I still have the problem.
To answer your questions and report effects -
If I use Bing, which I don.t like, no problems!
No BSOD - just straight to the black start-up screen.
Temp files cleaned out - I had already used Ccleaner but followed your suggestion and deleted others that Ccleaner hadn't.
All drivers updated by Ccleaner
Google Chrome uninstalled and re-installed.

Now the church page crashes either as soon as loaded or as soon as a scroll is attempted. When it restarts same again, but on 3rd restart, it worked fine. But as before, the problem exists only with this one page which works OK on my PC (Google Chrome).

- The problem may be with the church site. May want to check with others if they have same issue.

- Temporarily disable your AV and any extensions to see if any effect.

It only happens on my wife's PC. Works fine on mine.

Check that page for malware, makes no sense really.

Malware checker here
VirusTotal

Is it possible there is some malicious script on your wife's PC that is triggered by going to that page?
If there is, how would that be checked?

how about trying the TOR onion browser?

Well, problem fixed but unfortunately I don't know what i did, if I did do anything.
Thanks for all the help.
