Use Java 8 or 10. Forge needs to update a library to be compatible with J11 and coordinating the update for that library across the toolchain is expected to be a pain.

How long did you wait when it froze?

When you launch the client for this pack with the same mods what does it say?

Do you have Java installed? (I don't count the version of Java that the Minecraft Launcher packs in, as it's not set up in a way that your computer will recognize as Java)

Why are you using 1.12 specifically instead of 1.12.2?

Where did you download Forge from? Please give a url

Damage Indicators appears to be broken, also remove Optifine from your server.

Have you tried the solutions from the other threads?

The debug log does not just get extended when the server restarts, the old log gets compressed into a gz and a new debug log is made.

You have more mods there than Crayfish has on CurseForge... please give a url to where you are getting the mods.

You had your server up without restarts for about a month? Oof No I need the debug log, it has more detail.

Is it the exact same error every time?

Try Java 8 or 10

Update to 1.14.3 and Forge 37.0.57 and see if the issue persists.
