"Invalid player data" on realms.
It's been a couple of weeks now that I have been unable to play on my realms world. Whenever I try I am kindly greeted with "Invalid player data". This all started happening after I downloaded my SMP world to single player to add some datapacks and then reuploaded it. Other players can get in just fine but It wont allow me in. I've even tried deleting the player data to no avail. Pls help :(

Hello,
This issue is probably caused by corruption of the save, specifically relating to your player data. It is likely that when you tried to delete your player data previously, you missed something. The fact that other players can still connect is good, and indicates that you likely won't lose the save. I would suggest making a backup, and deleting your player data from the world/playerdata folder, as well as the file pertaining to you in world/stats and in world/advancements.
Hope that helps!

Also, make sure you are deleting the files for the correct UUID!
Is there a way I can tell who's player data is whos? I have 3 players in my realm and I dont want to delete their data if mine is the only one causing issues.
Yes, you can use this website to find your UUID.
Thanks so much for your help! I got it all back in order. It's a bit of a shame that I had to delete my advancements as well but it can't be helped. Is there any specific reason for this corruption happening, and a way to prevent it? I may need to download and upload my world more times in the future in order to switch and update datapacks.
I'd suggest you just make backups, so if it happens again, instead of deleting stuff you can just replace it with the older version. For example, make a copy of the whole save, then if anyone experiences this, find their old files and swap them in to fix it. This'll also protect you from other potential issues. It's not super common, but stuff happens and files get corrupted on occasion.
