Report this modpack to Curseforge There was a case about 1 year ago with Prominence and the used Resourcepacks/Shaderpacks - but this was a false positive But there were also cases outside of Minecraft where this virus caused a lot of problems The monsters, gunz and dinosaurs modpack does not have a source and disabled comments - this is sus - so just report it and run Antivirus tools on your system like ADW Cleaner/Malwarebytes

There are client-side-only mods in your server's mods folder REI and fantasyfurniture are mentioned - but maybe there are some more

Make a test without fusion

You can also make a test with a separate instance only using this mod If the issue is still there then it is definitely a mod issue - if not then maybe a conflict with another mod

Then I think it is some kind of bug with this mod - maybe try older builds

Same issue without JEI?

Hm I have no idea
