Hi Romain, thank you for reaching out!
We generally don’t allow increasing the column limit, as having too many columns in a table can negatively impact performance. The best way to proceed is to use the "Write to Table" feature and continue your workflow in a new table, which will give you access to the full column limit again.
If there are enrichment columns in your current table that you’re no longer using, deleting them can also free up space for new columns.
Let me know if I can help you with anything else :)
