I've got an issue running all Jetbrains tools on one of my machines, where the bundled version of JRE doesn't run – therefore, none of the tools start up. To overcome this issue, I have setup environment variables to point to a JRE version that runs correctly, ie. IDEA_JDK, RIDER_JDK, PYCHARM_JDK, etc. However, I can't find the env variable I should use for Fleet – tried FLEET_JDK, which doesn't work. What is the env variable I should use for Fleet?
