Or when I try to launch a pack I get "Failed to prepare instance (name of instance). because.. com.google.gson.jsonSyntaxExceptopn: java.lang.IllegalStateException: Expected BEGIN_Object but string at 1 column 1 pa" then it goes off the screen

Same

MichaelHillcox commented 10 months ago

Could either of you send over your instance.json file for that pack?

You can find this by going into the modpack on the app, then going to settings, open folder, then you should see the instance.json inside the folder that opens

Also, what do you see when you go to this url? https://launchermeta.mojang.com/mc/game/version_manifest.json

rbilicki132 commented 10 months ago

For your second question the first line is "{"latest": {"release": "1.20.2", "snapshot": "1.20.3-pre4"}, "versions": [{"id": "1.20.3-pre4", "type": "snapshot", "url": "https://piston-meta.mojang.com/v1/packages/b47ff274bd169d7c834b6fcce55f4950a7f49769/1.20.3-pre4.json"," And attached is the instance.json file for a failed install of genesis mod pack. instance.json

I can launch minecraft through the vanilla launcher and if someone sends me the mod pack file I can launch it through other launchers like multiMC

Thanks for that, can you also attach the following file:

C:\Users\rbili\AppData\Local\.ftba\bin\versions\version_manifest.json

rbilicki132 commented 10 months ago

it is attached version_manifest.json

MichaelHillcox commented 10 months ago

Yup, that would be the problem, can you delete that file and try and launch a pack again?

rbilicki132 commented 10 months ago

perfect thank you. Can you tell from the logs how it got corrupted/empty?

MichaelHillcox commented 10 months ago

Looks like it was just empty. I've forwarded this onto our subsystem developer to ensure fail safes are built into this process.

Having the same issue. Deleting my version_manifest.json file did not fix it. I am completely lost

If you are still having the issue, could you open a seperate issue for us? If deleting the file didn't work for you, you may be runnining into a slightly different issue.
