can you try removing the following file and see if it helps:

```
~/.local/share/recently-used.xbel
```

Also, explain what do you mean by "1. enable PDF preview (maybe)"

Deleting the file worked somehow once, but after a few restarts it was the same.

20s waiting, error:

```

kf.sonnet.clients.hspell: HSpellDict::HSpellDict: Init failed

This is known and fixed in 22.08. Once you open a few files, that file you deleted builds up again and starts slowing you down. I assume you open *a lot* of files.

For the second, I assume you mean "Document Preview" plugin. And for e.g when you open a markdown document, it shows you the preview for it. It is unlikely that this has any affect on startup. Especially because removing the xbel fixed it, so it's I am 99% sure the bug is with reading that file.

For now, I would suggest you to keep removing that file periodically. With 22.08, this problem is fixed but if you still face it, please reopen the bug.
