not sure if it helps but this is happening for me as well, same error, same results, it was working. And the next time I tried opening it it just sits there, then spits out that error log, and I force close the task. I also tried reinstalling as well as updating Java.

I just suffered the same issue, and found a solution to allow me to continue. If you kill the process, delete the .localCache directory, C:\Users\[USERNAME]\.ftba\instances\.localCache and relaunch the app, Then it works. It also rebuilds the directory, so it's not it's existence that is the issue, but something about the contents. Unfortunately, I didn't save a copy of the broken version for someone to analyze.

elpis4 commented 4 years ago

No, that didn't fix it for me unfortunately.

I am also experiencing this issue. Deleting my C:\Users[USERNAME].ftba\instances.localCache doesn't help it. It ran fine when my \instances\ folder was completely empty, so I slowly added files back until I determined that instance.json of FTB Interactions was the cause. I can point my vanilla Minecraft launcher to that folder and it works fine. Other pack's instance.json work fine; for example, if I remove FTB Interactions's instance.json the FTB App will open fine even with FTB Academy with it's instance.json still present in \instances. I have attached my copy of FTB Interaction's instance.json (renamed to instance.txt to be able to upload). Looking at this file, I can see why it is causing issues. I have not edited this file at all, so I assume this file was corrupted due to a bug. This is definitively the cause of the error for me. instance.txt

elpis4 commented 4 years ago

Wow, this fixed it. For me it was actually FTB Omnia, same messed up instance file.

instance.txt

bold0727 commented 4 years ago

I'm glad to hear that! I'm not sure if it should be closed considering whatever caused the corruption is still an issue though (and this fix barely works as you have to do a clean reinstall to play that modpack again =/)

elpis4 commented 4 years ago

True, having the instance.json corrupt like that is pretty bad, at least you can save your worlds though.

tkolarik commented 3 years ago

I have the same issue with a corrupt instance.json but it appears that way for any pack I download, is there a fixed version of instance.json I could copy and paste in instead?

gigabit101 commented 3 years ago

We released an update recently that might resolve this issue for you, Can you confirm that the latest version works for you?
