NullPointerException when sharing newly created directory in Nextcloud

⚠️ Before posting ⚠️

• This is a bug, not a question or an enhancement.
• I've searched for similar issues and didn't find a duplicate.
• I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".
• I agree to follow Nextcloud's Code of Conduct.

Steps to reproduce

Create anew directory, another subdirectory in there and navigate back.

Now try to share that by tapping on the share button. (I mean the people +1 one)

Is the same though if you share it via info - > share.

Reproducible.

Expected behaviour

No crash.

Actual behaviour

Cause of error

Same issue.
No matter the directory is already shared or not, when pressing on the share button (a person with a plus sign icon/ Circles with the first alphabet of shared accounts), it shows similar error message.
