LO fails to start with symbol lookup error

I’m on Arch Linux on a RPi 4 and after updating to Libreoffice-fresh 7.5.5-1 a while ago the program fails to start with the following error message:

/usr/lib/libreoffice/program/soffice.bin: symbol lookup error: /usr/lib/libreoffice/program/libutllo.so: undefined symbol: _ZTIN5boost6locale19base_message_formatIcEE

It has always been quite slow but was working without problems before. I completely removed the program and reinstalled it.

LibreOffice and libboost version do not match. If you already installed also the latest libboost then ask your distribution’s friendly package maintainer, they then likely built LibreOffice against a version of boost that is not present on machines running in the wild.
