Can't package my project when Niagarafluids is enabled.

Hi im wondering if anyone else has a similar problem to me?
I can’t package my game when i use the Niagarafluids plugin, for example when i use the “Grid2D_SW_ParticleCollisions” i get the errors that are in the picture.
i used a youtube tutorial, this one (https://www.youtube.com/watch?v=i9Bfg5H_fKM&ab_channel=renderBucket)
Maybe it can be because the plugin is in beta, or am i missing a bunch of steps and that results in errors?
