New Minecraft instance seems not to have directory

OS Name/Version:Ubuntu 20.04

Product Name/Version: Triton 2.3.2

I can create a new Minecraft instance for java edition, but when I mange the instance and try to uptdate it, its says it will download forge and then does nothing. If I look into the file manager its empty and in the / directory. Accessing it with WinSCP ist not possible.

Steps to reproduce:

  • Create minecraft java insance
  • Klick update in the status tab

Actions taken to resolve so far: I recreated the instance twice, upgraded it once before starting.
