Anyone else experiencing problems with 'Kanji Study' on Bluestacks?

[ICantSpeakJapanese]

Nothing to do with Bunpro, but I’ve been using it for a good few months and invested in the complete set to suplement Kanji study everyday. However, today I’ve been met with this blue screen.

Anyone else have the same issue? I sent away for a support ticket.

Ps. While I’m at it, any good dare I say better alternatives to Kanji Study are welcome, though I specifically would want something that would allow me to test input - or perhaps you have a reason to recommend not using input which you are welcome to recommend.

In fact half the time, I’ve found input based apps to be entirely innaccurate, accepting wrong answers, completely inaccurate or different shodo, or in one case a kanji that was completely different. All of the examples below were considered 5/5.

I use JA sensei for kanji study exclusively, though there is a lot more content to it.
With the free version (there is no ads just restricted content) you should be able to test the kanji section and see what you think of it. It’s pretty nice and would not have let your second and third example pass but the first one might be. If you like it has a one time fee of 50$ to fully unlock and you have at least 6000 kanji (all the jouyou and JLPT ones and maybe more) and all of them have example sentence.
Even though the sole creator decided to recently replaced most of the photostock with AI art, I can vauch for the quality and legitimacy of the writting of the lessons and text of the app. I have been using it since 2021 and all the audio is made by native plus all the cultural notes are really useful.
Even though the app is 15 years old, there is frequent huge content addition every 3 months or so. He recently updated the algorithm for kanji recognition and it’s way better.
Edit: I use this app exclusively on my Samsung tablet with a stylus for writting kanji.
