is not a valid sentence for at least two reasons.
It is ungrammatical for connecting, by using a 「と」,
a noun （ご説明） and a verb phrase （教えていただく）.
This is just not possible.
There is too much overlap in meaning between 「説明」 ("explanation") and 「教える」 ("teaching") that the sentence sounds awkward even if we ignore the fairly big grammar mistake mentioned above. I feel like saying that if you did one of the two, you would automatically be doing the other.
(Besides the two reasons above, 「と」 is considerably more informal than many J-learners appear to think. In fact, it is rarely used in formal speech for connecting nouns. We have 「かつ」, 「および」, etc. for that purpose, but again, those cannot be used to connect a noun to a verb.)
In conclusion, I would suggest that you drop one of the two items that you connected with a 「と」 to form grammatical and natural-sounding sentences such as:
I changed the 「いただいて」 to 「いただき」 because the te-form is also more informal than many users seem to think. You might want to read this Q&A regarding this matter.
