UM22.10 & Thunderbird

Before upgrading to 22.10, there was no problem opening .docx or .xls files attached to emails by simply clicking on them and LO would do the job.
LO 7.4 is activated, but I get the message that the file doesn't exist.
So now I need to download/save before opening... would rather do the reverse.
In the TB settings it is clearly indicated that they should open with LO 7.4 but it doesn't work. I can open .pdf without any issue, Atril doing its job.
Maybe just a small thing that I need to do. Do you know ?
