I was running to this problem when I wanted to upgrade my forge version to a recommended version which is 13.4.1448

But... I was running into a problem.

I cannot open my Minecraft (I can only open up my Launcher). When I press play button. Green tab of loading shows up and gone. The Launcher still open. No Minecraft window pops up. When I check the Development Console. I got this error code.

Here's the development console while I'm trying to run my Minecraft on forge 13.4.1448

KeiNett Launcher V1.404 (through bootstrap 1) started on windows...

Job 'Version & Libraries' finished with 1 failure(s)!

Some older version of forge (Older than 13.3.1381) I can install it. But forge version newer than 13.3.1381 .

I cannot install it at all. It keeps showing me up this error console over and over again. I'm now completely don't know what to do.

By The way I have tried replace scala complier and scala libraries already...

P.S. I'm sorry if I break any rules. feel free to delete it if this thread against any rules. I have read it and did not completely understand it (Because I'm Thai)

Sorry for that.
