Can't mount partition after change lable using minitool in windows 11

uz flag

I have dual boot windows and ubuntu while working on windows I changed the partition name in minitool wizard accidentally since the partition was not showing in the drive menu I tried.

When I tried to open the partition from the ubuntu its not mounting.

error:

mount: /media/External: cannot mount; probably corrupted filesystem on /dev/nvme0n1p5.

I tried to check and fix in gparted its shows:

e2fsck: Superblock invalid, trying backup blocks...

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
or
e2fsck -b 32768 <device>

I googled it bit and tried to restore superblock something. following this thread https://www.linode.com/community/questions/20599/how-do-i-fix-a-bad-magic-number-in-super-block-error

I'm afraid you have to try testdisk/photorec. You destroyed the metadata of the filesystem. Here a little bit wiki https://ext4.wiki.kernel.org/index.php/Ext4_Metadata_Checksums I have no other idea; but maybe someone other has. I'm sorry.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
