tabularray not working in Overleaf

[zoepierrat]

I cannot for the life of me figure out what I'm doing wrong. I get this error message

\l__tblr_template_caption-tag_default_tl ...ename
\hspace {0.25em}\thetable
l.72 \end
{longtblr}
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., \hobx'), type I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

! Undefined control sequence.

I figured it out - I needed to change the version of TexLive I was using to 2021 - not sure why but this seemed to fix it
