Freezes now and then 5.2.1.2, Windows 10

I like LibreOffice, but it freezes now and then with both documents and spreadsheets. Nothing in particular causes it; I am just working and it freezes. All I can do is delete it with taskmanager. I hoped the latest update would help, but it doesn’t.
I just bought a new computer, but it freezes on both old and new.

It tries to recover the file, but doesn’t do all that well.

Any advice? It can’t do this for most people or it wouldn’t survive!
Thanks.

Hello !

I think that you should use the still version, because it’s more reliable !
The last version is 5.1.5 !
