Hello Calc Team

When copying or cutting cells sometimes LibreOffice Calc crashes on macOS 14.5. I see this happening in the last few weeks, I am now on version 24.2.4.2, but don't know when the last update happened, so maybe some previous minor versions could be affected.

Yesterday I finally systematically tried to eliminate variables: 
- The crash is unrelated to the actual spreadsheet content, it happens even on an empty spreadsheet that hasn't been saved to disk yet in a fresh process. 
- The copied cells can be empty too. 
- There is no pasting required, the copying alone triggers the issue. 
- Cutting and copying behave the same w.r.t. to this crash
- Moving cells with drag crashes in the same way, I assume this is a "cut" under the hood.

The most minimal reproduction steps I could identify:

- Start LibreOffice
- Click File->New->Spreadsheet
- Select A1, copy the cell
- Select B1:C1, copy the cell range
- Select D1, copy the cell

--> Immediately the software crashes. No crash reporter opens, but the Document Recovery dialogue appears and says that LibreOffic crashed. It tells me that Untitled 1 will be recovered.

- The crash happens if I use command+C to copy, but also if I right click and click copy. 
- The crash happens with mouse or with keyboard selection of the cells.
- Copying many single cells into the buffer does not trigger the crash. 
- Copying many cell ranges into the buffer does not trigger the crash.
- Only the order of single cell copy (one or multiple), then cell range copy (one or multiple), then single cell copy triggers it.

I hope someone with an established community reputation has a macOS device and can reproduce. 

Finally here is my detailed version info:

Version: 24.2.4.2 (X86_64) / LibreOffice Community
Build ID: 51a6219feb6075d9a4c46691dcfe0cd9c4fff3c2
CPU threads: 16; OS: macOS 14.5; UI render: Skia/Raster; VCL: osx
Locale: en-GB (en_GB.UTF-8); UI: en-US
Calc: threaded

PS: I have first contributed with my reproduction steps to the thread at https://ask.libreoffice.org/t/crashes-in-24-2-4/106728/22. I believe that at least one or two people in that discussion observe the same issue I describe.

Steps to Reproduce:
1. Start LibreOffice
2. Click File->New->Spreadsheet
3. Select A1, copy the cell
4. Select B1:C1, copy the cell range
5. Select D1, copy the cell

Actual Results:
Immediately the software crashes. No crash reporter opens, but the Document Recovery dialogue appears and says that LibreOffic crashed. It tells me that Untitled 1 will be recovered.

Expected Results:
The copy buffer should contain the empty cell D1 and Calc should continue to run.
