Magic 10.10.5 - CustomData.tag NoSuchFieldException on Spigot 1.21.10

Hi,

My server runs spigot 1.21.10

Getting this error:

From what I understand 10.10.5 should support 1.21.10, referencing the 10.10.4 changelog:
"10.10.4
Add support for 1.21.9
Add support for 1.21.10"

Let me know if there is anything I should change or try on my end to help with this. Looks like M$ has been messing up the comp layer?

Regards

That's right, 1.21.10 should be supported. I wonder if this was some recent internal change- if you wouldn't mind, the exact server version would be helpful. Could you please paste the output from the /version command?

I'll try it out myself on latest Spigot when I get a chance. I generally only test on Paper these days, so it could be some difference there, too.
