Do you use any performance-enhancing mods (e.g. OptiFine) or custom server distributions (e.g. SpongeForge)?

no

This crash is coming from TaxFreeLevels, which you shouldn't even need in 1.20.4 because you can natively enable xp over level costs now.

Where can I enable that? one of the gamerules?

In the warp requirements. It's already the default.

Oh, I thought you meant that Vanilla could do that for all XP-related things.
