[Bug]: library 'NoneType' object is not subscriptable

[ghtesting2020]

Describe the bug

2022.6.14-brescia

with latest verson I am finally able to get to library view without crashing. I can now see the programs i add but when I click to play beside one it prints:

Traceback (most recent call last):
  File "/app/share/bottles/bottles/widgets/library.py", line 138, in run_executable
    exec_path=self.program["path"],
TypeError: 'NoneType' object is not subscriptable

yes i know library mode is very experimental. I am just reporting so it is aware. I am very excited for library and have been trying every version last 4 or 5 times hahahahah

To Reproduce

1. add program to library
2. go to library view
3. click play

Package

Flatpak from Flathub

Distribution
