It just happened to me on PS5, so it is not a windows only issue. It happened twice in a row while gathering items in Azys Lla for the Skysung Pickaxe. After finding this thread, I tried the steps mentioned by OP and it crashed:
1. Open Gathering Log.
2. Navigate to Skysteel Tool page. Selected and displayed oddly specific items. I don't have the Diadem step unlocked yet, so I believe it's simply the Skysteel Tool page.
3. Close Gathering Log.
4. Reopen Gathering Log and game freezes and crashes.

Submitted error report via PS5 interface in every instance of the error/crash.
