Additional context

Cannot invoke "String.equals(Object)" because the return value of "io.github.lmpactDevelopment.installer.setting.InstallationConfig.getSettingValue(io.github.Impact Development.installer.setting. Setting)" is null is the error that is returned when choosing any dropdown button or the launcher directory button.

Cannot invoke "String.hashCode()" because "\<local1\>" is null
is the error when pressing Install AFTER choosing a different option other than defaults.

Happens for exe and jar installers but only for the nightly installer.

If I don't select any options and just click install it works fine.
