Gaming mod here. We're pretty lax on being on or off topic. Your post would definitely be welcome on there, and I imagine on the technology community as well!
AskBeehaw
An open-ended community for asking and answering various questions! Permissive of asks, AMAs, and OOTLs (out-of-the-loop) alike.
In the absence of flairs, questions requesting more thought-out answers can be marked by putting [SERIOUS] in the title.

Yeah most communities aren't flooded with posts so as long as you've done basic searching yourself then it would be welcome in most places. So !gaming@beehaw.org for example.
Outside of the Beehaw instance, try !linuxquestions@lemmy.zip or !linuxgaming@lemmy.ml for the most relevant communities of people that might be able to solve your issue.
This community is meant for questions! :) Yeah, you may not necessarily get the best answers here than on a community that specializes on that sort of thing, but I don't consider that "off-topic".
