Just letting you know I am aware about the fact your antiviruses currently go crazy and report a trojan virus in the game. Don't worry, there's none, and this issue has affected other games which are using recent versions of LWJGL (the same thing Mojang used once, yes).
Infinitode uses LibGDX 1.12.1-SNAPSHOT (roughly the same as 1.13.0) and it is affected by the issue highlighted on their website:

I'm running exactly the same version of the game as you do and my (most recent version of) Windows Defenter does not complain (which is bad, because I don't even know which file is triggering the AV). Maybe Windows Defender team is currently experimenting with something and it causes this false positive, since not everyone is affected. Anyways, the game does no harm to your device, and if you are panicking and do not believe me - do reverse engineering, network monitoring or something (or ask someone else to do that) to prove I'm wrong, because a garbage in the antivirus' database is not the fact the virus exists and seems like some people blindly believe it.
Temporary fix
You can simply put the game out of the quarantine, mark it as "trusted", and it will become playable again (as a temporary fix). Please check the documentation of your AV software if you need to know how to do that.
Proofs
- https://libgdx.com/news/2024/10/gdx-1-13
- Issue on GDX-Liftoff github (a LibGDX installer)
- Issue on LWJGL3 GitHub
- Related discussion on Reddit
- Another game has the same issue on Steam
What now?
I'm searching for a solution / waiting for LibGDX/LWJGL3 update which should fix that - currently there's none. I also can't fix it myself because my instance of Windows Defender can not detect any issues in the game. The game will be updated as soon as we have a fix.
Going back to the previous version of LibGDX (which has no such issues) is not an option since the game depends on many features introduced in LibGDX 1.13.0.
If you have a solution, please let me know in the comments.
