After upgrade to 5.9, LibreOffice show a popup message with:
An error has occurred in LanguageTool 5.9 (2022-09-28 14:38:38 +0000): Document chache failed: Paragraphs: Endnotes: 0/0 Footnotes: 0/0 Headers/Footers: 12/12 Shapes: 0/0 Tables: 1695/1695 Text: 594/596 Unknown: 16/14
This is popup very frequently. Annoying.
Plus, LO raise 130-200% of CPU usage. It is draining my CPU and memory until crash. It’s needed to force close LO.
LO usage is only possible after deactivate LanguageTool extension.
