Texts only show first letter

Ever since the last update, my 14 has many bugs:

1. texts show up as one letter only: the first letter of the sentence
2. the word suggestion will replace my text with random words
3. I can no longer search a word to locate in previous texts
4. I can no longer search a word in my calendar to locate previous (or future)input; for example, I would search “haircut” to see my last appt date, but it no longer works

I have checked settings and there are no more updates listed. This has been a couple weeks - seems a bug fix should have happened already!
