Description:
Copying multiple cells causes Calc to not respond and memory use to increase rapidly and appears would use all available memory given time. I close the program before it goes over a Gig or so as I wasn't interested in causing OOM errors on my OS. The Calc application CPU stays around 8-12%.

There are multiple ways to reproduce this issue. However, making a new spreadsheet copying a 2x2 is enough to freeze it. There is no need to change the cells or for a specific spreadsheet file. I just installed LibreOffice and this laptop is brand new. I wouldn't expect problems like this.



Steps to Reproduce:
1. In the Windows search menu search "Offer suggested actions" and it should take you to a setting in System > Clipboard. Toggle "Suggested actions" on
2. Open Calc and new file or existing file whatever you prefer.
3. Copy multiple cells or copy a whole row or copy a whole column.
4. Attempt any other action. Calc should be frozen and will go not responding in a few minutes.
5. Check Task Manager and the Calc process memory usage will be climbing and continue to climb. Careful, I don't not know the max it will climb. It could cause OOM if left alone for too long. 
6. Stop Calc from task bar or kill the process from Task Manager.

Actual Results:
Calc stops responding and freezes

Expected Results:
Calc to copy cells to the Windows clipboard and continue to be responsive.


Reproducible: Always


User Profile Reset: Yes

Updating Windows and Laptop drivers (Just because)

This appears to be due to the Windows clipboard "Suggested actions" feature. When I disabled that feature the issue is now resolved. 

Workaround:
In the Windows search menu search "Offer suggested actions" and it should take you to a setting in System > Clipboard. Toggle "Suggested actions" off. It says this is for getting suggestions for actions when you copy a date, time, or phone number.

I found the workaround from the suggestions in this thread.

Request: Fix the compatibility issue between LibreOffice and Windows clipboard features such as the "Suggested actions". It also seems the clipboard history feature might affect LibreOffice as well based on other reports, but I didn't test enabling that feature.

P.S this is my first bug report. I hope I am doing this correctly.
For the priority, I thought normal fits because of the high visibility to users because Windows is setting "Offer suggested actions" is enabled by default. It wasn't easy finding the answer and I could see new users giving up on LibreOffice if this is their initial experience. The issue was starting to disappoint me to switch to something else. Anyway, the clipboard feature is new and I haven't been able to use it to comment on it's value, but it looks nice from what I have seen. It is a shame I have to disable it for LibreOffice.
