I've talked about this with a number of other new vegans under other headings on this board…
…many of them mistakenly think they have a bean-allergy, but they're really just not accustomed to cooking beans.
Beans of any kind require much more cooking than meat: chickpeas boil for a full hour before making hummus (whereas, yes, I realize that some people make hummus with the beans raw out of the can... and that is a formula for terrible indigestion).
Beans with a thinner "skin" can be boiled more rapidly than beans with a thick "skin" (this "skin" is the part that has evolved to resist insect-predation, and that is hard to digest). Black beans break down rapidly, whereas fava beans are extremely difficult to make digestible at all.
Never eat beans raw out of a can; never eat tofu raw out of a packet; never eat soaked beans raw out of whatever you've been soaking them in. They all require very significant cooking times.
If you're accustomed to cooking meat and potatoes, this may be unfamiliar.
To try something radically different for a while, you can switch to a non-bean source of protein such as Job's Tears [Coix lacryma jobi] --and I assume you'd supplement that with vegan protein powder, as you're evidently into a pretty heavy lifting schedule.
There's really nothing wrong with soybeans, and there's nothing wrong with Tofu --but there is a cultural misconception that these foods can be eaten uncooked. I have been to "Asian" restaurants in the western world that serve some of these ingredients in a format that would be scoffed at in Asia. Canada is pretty much the worst place on earth for this. In Canada, I have seen kidney beans and chickpeas served straight out of the can, and tofu spooned straight out of the plastic packet, etc. --as these beans were equivalent to a piece of lettuce (that restaurants could serve without even rinsing!).
To offer a very different example, I don't think that anyone even tries to digest uncooked Okra or Leeks --but these are, simply, more culturally-familiar foods for most of 21st century western civilization. We know that you can't eat leeks the same way that you eat lettuce --but we apparently don't know this about something as tough to digest as kidney beans (etc. etc.).
Job's Tears, what the plant itself looks like:
Kidney beans, by contrast:
