Hello everyone dear guys, I recently started using Anki Droid on my computer, I use old versions because I have Windows 7 and it does not support new versions Ankidroid. Please help me how to fix these errors so that I can export all my cards in the future

That’s the problem, you’re using an old client of Anki and you’re syncing it with the latest version of AnkiDroid.

I’d recommend downgrading AnkiDroid to where it correlates with the old client you have. I’d recommend these versions from GitHub, and experiment which versions work - 2.1 · Releases · ankidroid/Anki-Android · GitHub

If you’re staying on an old version due to Windows 7 – you could still update quite a bit from 2.1.15. Install & Upgrade - Anki Manual

The last Anki release that supported Windows 7 and 8.1 was Anki 2.1.49.

That’s much more likely to be able to sync with the current version of AnkiDroid.
