Thanks for the version info—that helps a lot.
If Anki 25.09.2 is still freezing when you open Browse even with add‑ons disabled (Shift on startup), then:
- The freeze is not caused by AnkiHub or the AnKing MCAT deck directly.
- We need to (1) rule out file corruption, then (2) get you a clean re‑import of the deck.
Let’s go in very small, safe steps.
1. Make a full backup (very important)
Even if Anki is freezing, if you can open the main window at all:
- Go to File → Export.
- In “Export format” choose Anki Collection Package (*.colpkg).
- Make sure “Include scheduling information” is checked.
- Click Export and save it somewhere safe (Desktop, Documents, etc.).
If this export fails or Anki freezes before you can do it, let me know.
2. Check if the problem is only this profile
If you can get Anki to open, try creating a temporary new profile to see if Browse works there:
- From the main screen, go to File → Switch Profile.
- Click Add → name it something like
Test. - Open this Test profile.
- In the Test profile (which is empty), click Browse.
What happens?
-
If Browse works fine in the Test profile
→ Your installation is okay; the problem is likely something corrupted in your main profile (possibly the bad MCAT import). -
If Browse still freezes even in the Test profile
→ The issue is most likely with the Anki installation / system, and you’ll need to reinstall Anki (step 3) and possibly contact the official Anki support.
Please tell me which of those happens.
3. Reinstall Anki (if Browse also freezes in a Test profile)
If Browse freezes even in the empty Test profile:
- Go to https://apps.ankiweb.net and download the latest stable installer for your OS.
- Restart your computer.
- Run the installer and let it overwrite your current Anki (your data are stored separately).
- After install, start Anki with Shift held down.
- Try Browse again in:
- The Test profile
- Then your main profile (if the Test profile works).
If after a clean reinstall + Shift‑startup Anki still freezes in Browse, this is now a core Anki issue. At that point, I’d strongly recommend posting on the official Anki help forum with your system details and version; I can help you draft that if you’d like.
4. Once Browse works: fix the AnKing MCAT deck
Only after Browse is working (even if it’s just in your main profile) should we tackle the broken MCAT deck:
- In your main profile, from the main screen, right‑click the AnKing MCAT deck → Delete.
- Confirm you are deleting only that deck.
- Restart Anki.
- Re‑download the official AnKing MCAT .apkg from the purchase/source page.
File → Import→ select the newly downloaded file.- Accept the default note type and deck mapping.
- Do not remap to other AnKing note types.
- Before enabling any add‑ons:
- Open Browse.
- Select the AnKing MCAT deck on the left.
- Confirm that the fields on the right contain text/images and the cards no longer show “no cloze 1 found on card”.
After that, if you want to sync it with AnkiHub, follow the docs here:
What I need from you next
Please reply with:
- Were you able to export a collection backup?
- In the Test profile, does Browse open or still freeze?
- If you tried reinstalling, did Browse start working in the Test profile?
Once I know those three things, I can tell you the exact next step to both stabilize Anki and get your paid MCAT deck working.
