Before you read i want to let you know that the version 1.14.4 is not version that has a bug in it. I just had to choose one to continue on because you can´t choose a Forge version...
I was trying to load a regular Forge version (1.8) to play and test a mod. However there is a problem. If I click on the Play button it may seem as it would load but in reality when the loading bar is full, the launcher closes and opens just a few second later with a message. It says something like: "This version cannot be loaded. Sorry for the interruption." But the thing is that I didn´t even do anything special. All I did was clicking the Play button. (If you are wondering wich mod I used then here you go: Lucky Blocks Mod)
Thank you for your report!
However, this issue is Invalid.
Your game, launcher or server is modified.
If you can reproduce the issue in a vanilla environment, please create a new ticket.
Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.
Any plugin issues need to be addressed to the creator of the plugin or resource pack.
If you have problems on large servers, such as The Hive and Hypixel, please contact them first as they run modified server software.
