in fact there is never reason to unsintall Voicemeeter (except to update to new version). All is a question of configuration.
In your first picture, the red numbers displayed in the Virtual Input section show that they might not work.
It seems you have modified default internal latency of the VAIO (Virtual Audio I/O) of Voicemeeter to 512 samples.
This value is too small to work (in 99% of cases) because it asks to applications (including Voicemeeter) to manage audio buffer < 170 samples, wich is usually not the case under Windows, except with special audio applications (and your Voicemeeter is using 256 samples buffer) so you get no sound coming from application, and application get no sound from Voicemeeter (because these application are using bigger buffer, and virtual I/O simply cannot manage them).
Tweaking Latency and buffer size in Voicemeeter required specific expertise. We recommend to not change this kind of option, before having read this note:

in case of problem, just go back to default settings regarding Buffer size / latency / engine mode
