It’s really a pain when the word you mistype is actually a word. Spellcheckers don’t pick up on that. Beta readers can help. I’ve also found that reading my work aloud can help me catch some of those errors.
I use LibreOffice and there is an extension called “Language Tools” which can provide grammar checking. It does catch a lot of those correctly spelled but incorrect words, and many other grammar issues. You can also add to the list if there is a grammar error that is not listed.
