Hi, could you please check if pre-release version can help?

https://github.com/Flow-Launcher/Prereleases/releases/tag/v1.20.0.12046

I wonder if this is fixed in #3655 already

i have the same issue but the exception is different:

System.AggregateException: A Task's exception(s) were not observed either by Waiting on the Task or accessing its Exception property. As a result, the unobserved exception was rethrown by the finalizer thread. (Object reference not set to an instance of an object.)
---> System.NullReferenceException: Object reference not set to an instance of an object.

Hi, AggregateException is already fixed in #3627. And could you please try pre-release version?
