Manjaro install on my SSD corrupted after trying to expand it in size with a live environment

I was trying to expand my Manjaro partition, but the KDE partition manager returned with an error and now it says that the partition type is unknown.

Is there any way to recover my data from this partition?

Provide Information:

Hello, I am entirely unable to boot into the install. I only have the live environment, would you like for me to give you the outputs of the live environment?

Yes

Even inside the live environment it is possible to gather a lot of needed information.

how exactly?

which one?

Errors during reformmating partitions are usually desastrous. If you have not a backup of data you wish to retrieve you would need professional software to rescue some data. Most likely, very little chance. Take it as lesson and backup your data, next time. I guess you should re-install Manjaro from the scratch.

Unfortunately, I didn’t save the error message.

If I remember correctly, I expanded the partition to the right 500 megabytes (it was a tiny section that wasn’t allocated, could this be why the install bricked?) and then shifted it to the left by 15 megabytes.

As for recovering lost data, have you any recommendations for such software?

Okay, I got the output of it

this is the partition that became unallocated /dev/nvme0n1p5

Okay, I ran the command as root.
