Unexpected end of JSON Input Error after installing nRFConnect for Desktop 3.11.1

I've just installed a new version of nRFConnect for Desktop, version 3.11.1. When I try to launch Toolchain Manager, I get an error "Unexpected end of JSON Input" error message. How can I fix this. I'm on a very tight development schedule. Thanks in advance.

  • Hey Edvin, I'm running Windows 11. I did have v3.11.0 running for several months, but when I tried to upgrade, that's when it failed. I've uninstalled and reinstalled several times and still I get the same error message. But it seems the garbage characters in the title bar change everytime, like there is a bad pointer assignment somewhere.

    Regarding the toolchain json file you requested, it doesn't exist anywhere in my User folders. I attached a screenshot of the folder you indiciated. And a screenshot of a search for something close to that file name.

    I did generate a system report. The BLE LE App seems to install and run just fine. But I cannot get toolchain manager to run. BTW, I found some logs related to the latest upgrade attempt. Not much there for me to go on. But maybe it will help you.

  • Did you find a JSON file that belongs to the toolchain manager? If so, can you please upload a copy of it here? I don't know where it is located in MacOS, but probably close to where the nrfconnect-system-report-2022-06-03T16-49-03.txt was generated.

    BR,

    Edvin
