Clipboard manager bug?

Hello, I have encountered a bug with the clipboard manager, on Macos sequoia 15.6, all of a sudden all my clipboard history are gone, including my saved clippings. I also note that every time i click on the star to save a clipping, btt crasches/restarts.
Anyone else experiencing this? On BTT 5.566

could you tell me what files prefixed with BTTClipboardManager you can see in this folder?

~/Library/Application Support/BetterTouchTool

(go there via Finder -> Go -> Go to Folder, make sure to include the ~)

BTTClipboardManager_20241210.20251507sqlite
BTTClipboardManager_20241210.20251507sqlite-shm
BTTClipboardManager_20241210.20251507sqlite-wal
BTTClipboardManager_20241210.sqlite
BTTClipboardManager_20241210.sqlite-shm
BTTClipboardManager_20241210.sqlite-wal
BTTClipboardManager.sqlite-shm
BTTClipboardManager.sqlite-wal

And these hidden folders:
.BTTClipboardManager_20241210_SUPPORT
.BTTClipboardManager_SUPPORT

Could you try to quit BTT, then make a backup of these - afterwards delete them? Maybe there was an error during migration from the old format to the new format. If you delete the ones with the 20251507 extension, BTT will try to migrate again.

Tried that but same result. I took a look in the Logs/xxx.log file and saw this: (removed file path for privacy)

these are helpful, I‘ll check in detail later today!

Could you check whether BTT 5.568 helps with this?

Yes 5.568 works! Seems like all the history and saved clips are back, and saving new ones work too! Glad that this works again, I use it all the time.
