I tried fixing this with https://github.com/acts-project/acts/pull/3471 but sadly that does not work

[AJPfleger]

Discussed points in the developers meeting: @paulgessinger: ways to workaround:

• run on multiple threads but then output gets complicated (@AJPfleger investigated already)
• make ODD lifetime limited and call afterwards explicit delete function

@andiwand: maybe pytest captures whole stack and the problem is there

[paulgessinger]

I think this is resolved now @andiwand?

[andiwand]

should be yes
