Cannot add private keys on my Galaxy Tab 9

[cnaslain]

Bug description

I cannot import private keys with ConnectBot

Steps to reproduce

Open ConnectBot

1. Go to Menu > Manage keys
2. Click on Open (folder icon)
3. select a private key file
4. The app does nothing (50%) or crashes (50%)

Expected behavior

The app should be able to open/import the private keys without crashing.

Android device

• Device: Samsung Galaxy Tab 9 Ultra
• OS: Android 14 / Version One UI 6
• ConnectBot Version: 1.9.9

Additional context

• I tried with rsa 2048, rsa 4096, ed25519 private keys. Same behavior.
• I tried with my Google Pixel 6 and the same version of ConnectBot: No issue importing keys.
• I don't see ConnectBot in the available list of apps that could/should have access to files (Permissions > Files); only the system file manager (same for Pixel 6). I suspect that ConnectBot can't open the selected privated key file.
