Lagging when working with large scores

If you are working with a large score for around 15 minutes. Musescore starts lagging and starts claiming it doesn't react. Especially when you have saved the file

Steps to reproduce the behavior:

1. Open any large score (for instance a large string orchestra with a lot of woodwinds, brass, and percussion)
2. Work on it for 5-10 minutes on the score
3. Save the score
4. Continue working on the score
5. Eventually (with different timing) it will start to claim it's not working and starts to lag on every command you put in.

Expected behavior
Simply that it doesn't become slower the longer you work (very basic, I know)

Platform information

• Asus TUF gaming laptop running Windows 11

Additional context
A possible flaw is that I opened old musescore files. Saved on musescore 3.6.2 and opened them with musescore 4 (beta)
