Can't open File Explorer

First post so hope I don’t break any rules. I have windows 11 (23H2) and had to do some reinstalls after Win update corrupted boot menu. Have downloaded Libre Office 24.2.6.2 and now can’t access Windows File Explorer.

If I open Libre Office and click ‘Open file’ my file explorer is there with all contents, almost a mirror image of my Windows File Explorer. Have also tried latest version of Libre.

Would really like to access my File Explorer as normal if anyone can help. Thanks.

Panic over!

I’ve managed to restore through ‘Acer Documents’.
