The cause appears to be made by the server watchdog, which is forced to crash the server if it detects a tick taking too long. In order to prevent this, you will need to go into the server properties and set the watchdog timer to -1 (disabled).

It has been improved, but it will still crash.

Not sure if that makes sense...

The Server Watchdog is designed to stop a server if it thinks a tick is taking too long to elapse, which is set to 60 seconds. In the case of modded, it might not be long enough, especially when a pack gets big enough and you switch dimensions.
In order to prevent this, you need to go into server.properties, find the max-tick-time value to -1 (disabled).

If this is a single player world, there might be something else at play, considering that you mention the screen "turns black".

I will pay attention again.

Closing due to inactivity. This crash was caused by the server watchdog.
