I hope you can help me fix this, as I don’t see any obvious errors. Thanks for you help.

still problem?
I’ve installed HS using this instructions for deck tracker: https://github.com/borisbabic/hearthstone_hdt_linux
only after this I’ve found Lutris and linked HS in it
this instructions are very different: win7 instead of win10, 32 bit instead of 64bit
