Open a bug report in KeepassXC’s repository, maybe it’s a big in their code. Or they’ll tell you that the bug is in proton pass, and you can report it there too so that they know about it and can fix it. Maybe the KeepassXC team can give you a workaround too

My English is very poor for technical explications.... I search the issue in KeepassXC Github but I don't found similar solution.

Yes, I export to CSV but when I import in KeepassXC, only one column appears.

Use a soldering iron, not a mic. A mic won’t get hot enough.

I had thought of replacing the microphone with a hammer.... will work??

awesome.... Thanks....
