Seems like this is caused by us including yaml 1.33, which is the version used by com_fasterxml_jackson_dataformat_jackson-dataformat-yaml 2.14.0. ViaFabric is including a newer yaml version (2.2), which is likely what's causing the issue here - marking as confirmed bug. For now, you can use an older version of Geyser which you can download under the artifacts tab here: https://github.com/GeyserMC/Geyser/pull/4495/checks

Could you test the linked PR and see if that resolves the issue? You can download it from the Checks tab.
