My Technic Launcher wont open (MAC)

Question

I have recently updated to macOs Catalina, and i wanted to reinstall technic launcher to play with my friends. I already have java installed, but when i open the .jar file, it pops up on my dock and disappears twice. When i check the logs there is usually one log for each time i open it, along with nothing in the surrounding folders. I have tried to 'reinstall' technic multiple times.

Yeah, you need to use Java 8. You are probably using Java 13.

Direct Copy/Paste from the discord bot:

Forge, Technic Launcher, and Minecraft do not support Java 9+. Follow either the manual or script instructions to remove it and replace with Java 8: Script 1. Close the Technic Launcher. It cannot be running! 2. Download this file: https://download.uskarian.net/scripts/mac-delete-java9.command 3. Open terminal 4. Copy and paste:

chmod +x ~/Downloads/mac-delete-java9.command

5. Copy and paste:

sudo ~/Downloads/mac-delete-java9.command

If it asks you for your password then type in your password.  You will not see text being entered as your type, but it is being entered! Once you've typed your password hit enter on your keyboard. 6. Download Java SE Development Kit 8u191 from http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html 7. Install the jdk-8u191-macosx-x64.dmg you just downloaded. OR Manual 1. Close the Technic Launcher. It cannot be running! 2. Open terminal 3. Copy and paste:

sudo rm -rf /Library/Java/JavaVirtualMachines/jdk-{9,10,11,12,13}*.jdk/

If it asks you for your password then type in your password.  You will not see your password being entered as your type, but it is being entered! Once you've finished typing your password hit enter on your keyboard. 4. Copy and paste:

sudo rm -rf Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin

5. Copy and paste:

sudo rm -rf /Library/PreferencePanes/JavaControlPanel.prefPane

      So basically, I am running into really strange rendering issues such as in the video i linked below
      https://www.youtube.com/watch?v=_0wqhXuOikM
      This is one of many cases I have had of this specific render error, I have had these appear randomly across the map both moving and static. Also many chests render invisible at some times and mobs can become a combination of different textures such as in the photo i attatched with the alchemy chest. The textures also sometimes change while playing, normally when i cross chunks.
      Also typing commands, softlocks the game inside the chatbar only way to make it close is by minimizing the game and maximizing it again or when your player get pushed or teleported..
      I also would like to point out that this issue does not appear in other modpacks than classic.
      Tried both openjdk 7 and openjdk 8, both got the same issues but with jdk7 the effects are not as bad.
      Someone got the fix for this or know where to start looking?
       
      OS Manjaro Linux, latest build with KDE.

      I installed the Final Stand modpack and its in my .technic folder but after it downloads there is no open button, it just says install. I tried doing that but nothing changed.

      I have been trying to play mod packs through the Technic launcher, but whenever I download and play a pack, it opens up Minecraft in the very bottom right of my screen. When the game loads into the title screen, when I fullscreen there is no buttons or words. Also, whenever I enter a world and I try to put it into fullscreen, the screen bugs out and starts going crazy. (almost like if the camera starts spinning in a circle). I have tried looking for fixes but it seems as no one else has this problem. I am in desperate need for help, as I get little to no FPS when not in fullscreen. (Yes, this happens in all the mod packs I've checked so far.)

      Hello !
      So here's my problem !
      I imagine that it is me, who is made a mistake but good ! When you don't know! You might as well ask for help !
      I tried to create a Modpack for my friends and me. Except that when the Technic launcher installs it, the game launches in Vanilla.
      I attach to you the link of the archive which I use for the Modpack.             https://a-11.1fichier.com/p615904169
      The Modpack is in 1.12.2. It is surely important to specify it !
      Thank you in advance for your help.
      EllisAkap.
       
      Ah ! And ! Sorry for my english, if it is not perfect ! Being French, it is not my main language.

      So, I'm trying to download Technic Launcher, everything went smoothly up until the point I actually downloaded it.. I went to the "Discover" tab only to see it completely blank, all of it was white except the top and bottom boarders of the launcher, my profile picture also won't load if that gives any more insight into my problem.

      Mind helping, anyone?
