I think they found a workaround in this post for the same error Question - Tile palette create error… - Unity Forum

3

they said “Then drag and drop the prefab into the tile palette window.” but i dont know where abouts to drop it as it doesnt let me drop it into the tile palette window.

After you created your palette, manually add a sprite renderer component to it.

Can confirm, this is the solution!

This error happens whenever you use an external drive.
This video demonstrates that you get the error ArgumentException: Unable to set invalid palette
whenever you use external drives. The issue goes away when you use the internal drive. Look right around the 1:45 mark

I had this same problem, and I found the solution.

1st First solution: This probably happens because Unity is on an External HD. So, creating your project on a Local Disk, there will not be this problem.

2nd Second Solution

If by chance you want to keep your Project on your External HD. Just click on Save project when the error appears.

It worked for me. Just like that: The error message appears. You click on SAVE PROJECT. In the same test, the Bug fixes itself.

That’s the problem. I plan to edit my game on an SSD so my friends can play it later. Both solutions are proved useful, you are a genius bro!

And it may because the file you store your project was set “just read”(may differ due to translation mistakes),just turn off that and try again.
