Hi! I've downloader the server file from the curseforge launcher, but encoutered this problem. When I execute the server .jar or the .bat file I made, the program launches and instantly crashes within half a second. In the lastest log, I am able to find this line:
[main/ERROR] [mixin/]: Mixin config antiqueatlas.mixins.json does not specify "minVersion" property
What should I do in that case? The forge version is 1.16.5-36.2.20, same as the client I have. Haven't modified anything, and am not sure of what to do next.

Any ideas?

Also having this issue. SS attached of my terminal.

#482 This is your real issue.

Had this issue as well:

I could not find the answer anywhere so I tried to uninstall my latest version of Java (Java 8 update 341) and then download any other previous update of Java 8. I picked update 292 and it actually worked. I'm pretty surprised that there isn't any update on this issue.

I got the previous java from this link: https://www.openlogic.com/openjdk-downloads

I hope I helped someone :)
