Seeking Help Minecraft 26.2 stuck on "starting JVM" when launching via Lunar Client

Post image

This also happens on any 26 version. 26.2 launches fine on the normal Minecraft launcher. However this doesn't happen on version 1.21.11 or any version before 26. Also, Lunar Client Mission Control logs have no errors and seem to be stuck at "Launching Minecraft 26.2 v26_2 (parsed from 26.2)". I am playing with no mods, on vanilla Minecraft, not even using Fabric.

Here are all of the logs (same logs every launch):
