Is it possible that the Latin conjunction "ergo" was derived from the dative singular of the Greek word "εργον", meaning task?

    What do you mean by "possible"? Like, alternate reality possible, consistent with the evidence if we didn't know the answer possible, or a possibility that we should consider now possible?

The Latin ergo is connected to words about proceeding directly:

Equivalent to an adverbial derivation from *ēregō, presumably ex- +‎ regō, with sense similar to cognate pergō (“I proceed”), from Proto-Indo-European *h₃reǵ- (“to straighten; right”). See also ergā. Compare with the adverbial use of ē regiōne (“directly, against”), with the same elements. Wiktionary

The Greek ἔργον is from words in precursor languages also meaning 'work':

From Proto-Hellenic *wérgon, from Proto-Indo-European *wérǵom. Cognates include Old English weorc (English work), Avestan 𐬬𐬀𐬭𐬆𐬰𐬆𐬨‎ (varəzəm) (Persian وَرز‎ (varz)), and Old Armenian գործ (gorc). Wiktionary

I'm no expert but since neither etymology is listed as especially speculative, it seems that the experts do not think there is a connection between the two.
