mount can't read superblock on /dev/sda5

Notebook fails to boot. I started it with a live USB Ubuntu 20.04 and tried mount /dev/sda5 but receive this error: mount: /mnt: can't read superblock on /dev/sda5 So I tried the commands below: ubuntu@ubuntu:~$ sudo fdisk -l /dev/sda Disk /dev/sda: 931,53 GiB, 1000204886016 bytes, 1953525168 sectors Disk model: WDC WD10SPZX-21Z Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: gpt Disk identifier: 8798743C-1711-4EC3-9829-F392872338D3 Device          Start        End    Sectors   Size Type /dev/sda1        2048     206847     204800   100M EFI System /dev/sda2      206848     239615      32768    16M Microsoft reserved /dev/sda3      239616  408477642  408238027 194,7G Microsoft basic data /dev/sda4  1951424512 1953521663    2097152     1G Windows recovery environment /dev/sda5   408477696 1951424511 1542946816 735,8G Linux filesystem Partition table entries are not in disk order.
