ANR Issue - Request for confirmation of fix in v5.4.2

[lucian-zhan]

Hi, I‘ve encountered two Application Not Responding (ANR) issues in my project. I would like to confirm if this known ANR has been addressed in the latest release (v5.4.2), or if it remains unresolved.

Any information would be greatly appreciated. Thank you!
