This is because resizing a partitioon in GParted does not only resize the partition itself, but also the file system laid out on this partition. Resizing the file system means moving around lots of data on the disk and reorganizing the metadata used to manage the available space and the data stored on the file system. In the middle of this process, the metadata on disk is very likely to be inconsistent - and since you have aborted the operation while it was running, you havew inconsistent metadata right now.
These metadata structures sture which file is stired in which diretory, which file system blocks in whoch order belong to which file, when each file was last accessed, how mich free space you haven, and so on. Since these structures are not consistent with the data on disk (and maybe not even within themselves), your partition is unreadable now.
If I remember correctly, there is even a confirmation dialog after you've clicked "Abort" that tells you thatz severe damage to your data could occur if you abort now, and offers you the option to continue the operation... So the safe way would have been to wait for the resize process to finish and then revert back to the original partition size!
Maybe you'll have a chance to recover your files using e.g. photorec - despite its name, this tool can recognize and recover much more than "only" image files.
