About という理由で
という理由で is a phrase that is used when giving reasons for (A). (A) may be a range of different things, from what happened, to what one's opinion is. Due to という quoting the previous statement as being the 'reason', という理由で puts quite a bit of emphasis on the reason itself. Because of this, the expression is quite similar to 'being that' in English.
The case marking particle で will be used after 理由 to show that 'with' or 'by means of' that reason, (B).
Fun Fact
Almost all cases where という理由で will be used may be replaced by というわけで. However, the reverse is not true.
The reason that わけ may be used for 理由, but 理由 cannot always be used for わけ (especially at the beginning of sentences) is because わけ is another way of reading the kanji for 理由. However, the more common kanji for 訳 will never be read as りゆう.

To me the “Fun fact” contrasting 訳 and 理由 is borderline inintelligible:
The reason that わけ may be used for 理由, but 理由 cannot always be used for わけ (especially at the beginning of sentences) is because わけ is another way of reading the kanji for 理由. However, the more common kanji for 訳 will never be read as りゆう.
I have zero idea why the fact that 理由 is a secondary spelling of わけ helps understand the nuance between the two.
I already complained about that in the past but I find that bunpro always taking the stance that meaning “comes from kanji” or that kanji comes first and the reading choice is a post-hoc decision is frankly a bit absurd and in this particular instance really confusing IMO. The word わけ came first, the choice of spelling is only relevant for the written language (and わけ is very often spelled in kana anyway).
All that to say that I after re...

I agree with simias, the difference is not explained that well.
という理由で、この企画はキャンセルすることにします。 (Unnatural)
After reading through the explanation, the only thing that comes to mind is that it should be
そういう理由で since it is at the beginning of a sentence. If I rephrase it like that is it then natural to use りゆう? Or is わけ the only correct answer?Maybe the Fun Fact is just pointing out that you can read the phrase という理由で as both わけ and りゆう but という訳で not as りゆう.
