I believe they are introduced in latest (non LTS) Unity versions? 2023 or V6

thekiwicoder0 commented 2 months ago

Yeah they were introduced in 2023.2. Anything prior will get this error. The minimum version on the package is set to 2023.2.0f1 which should prevent being able to install it on incompatible versions.

Closed as no intention of supporting older Unity versions - reason being, those versions have a bunch of UIToolkit bugs which require their own workarounds and will become a maintenance nightmare
