Crash code after accidentally deleting notes in Notes app: is it possible to retrieve the notes?

Hi, please help! I accidentally deleted over 40 notes. When I pressed undo, the app crashed and produced this crash code:

My understanding of this coding is below beginner. I'm using e OS because I've been wanting to move away from google products whenever possible. A Fairphone user for many years, I was excited to see there was an alternative when it was time to finally get a new phone last year. I got help from a kind user on the e community forum to figure out to post here on gitlab. They told me:

"you’d create a gitlab entry if there’s none yet for “getModified() on a null object reference”

java.lang.NullPointerException: Attempt to invoke virtual method 'java.util.Calendar it.niedermann.owncloud.notes.persistence.entity.Note.getModified()' on a null object reference

but I have difficulties reproducing it with newly created (then deleted, then undo-ed) notes"

I searched but did not see anything posted along these lines.

I was not logged in with a Murena ID account and did not have the notes on a cloud.

As you might guess, seriously, any and all help is appreciated.

Most importantly to me, is it possible to retrieve the notes?

Thanks so much!
