Starting LO from Linux command line - odd behavior

For a long time I have started Writer (and Calc, Base) with commands like soffice myFile.odt. Libreoffice opens the file, and the console returns to the prompt, ready for another command. This is with Debian 11 “Bullseye” on a Thinkpad.
I got a newer Thinkpad and installed Debian 11, which includes Libreoffice. Now when I use the same command, the console is “tied up” and unresponsive until I close LibreOffice. Also, the next time I start LO, the document-recovery dialog comes up even though I saved and closed the document and closed Libreoffice normally.
I want the newer computer to work the same as the old one. What’s going on? Thanks for any ideas.

I don’t know, if anything changed in LibreOffice, but the traditional solution in Unix is a trailing ampersand & like
soffice file &

This starts any command in background. But please be aware: Console is shared for output.

Thanks, that’s a good point and pretty easy to do. And for some unknown reason, the strange behavior of “recovering” every file upon reopening has resolved itself.
