I had a Google Play user report on this problem but was never able to reproduce it.
I have several theories:

• Either it's from Kotlin, there is a closely related issue but the version is higher so it should be solved. StackOverflow in DispatchedContinuation Kotlin/kotlinx.coroutines#2371
• Or it's a problem with a bad translation.
• Or it's a problem with a specific type of device / android version

But the main problem is that I can't reproduce it, so I updated the Kotlin libraries and plugins for the next build but I don't even know if that will really solve the issue.

[J-Jamet]

Maybe the bug is related to #509 (comment) because the definition of a complex XML drawable does not work on Android 8 and loops the internal image parser.

[J-Jamet]

I also removed the request for write permissions, which is normally unnecessary with SAF. I will create a test version and upload it here and you will tell me if the crashes happen again.

Can you tell me if it works with this test build?

[SrgkS]

The databases are not opened (probably due to unavailability of write-permission).

Version 3.0.2 works fine, what changed in 3.0.3 (3.0.4)?

[J-Jamet]

git diff 3.0.2 3.0.3

[J-Jamet]

The databases are not opened (probably due to unavailability of write-permission).

Permissions don't normally change anything, so the fact that there are no permission shouldn't prevent opening.

[J-Jamet]

Can you tell me if it's fixed with version 3.1? https://github.com/Kunzisoft/KeePassDX/releases/tag/3.1.0

[J-Jamet]

I have no more crash feedback in the play store console so I guess it's resolved for you.
