This image is the best example of the problem I am having:

It is a text issue and as far as I can tell, that is it. I am not sure I really can make this more clear by providing more information at this point (both due to lack of access to the problematic PC for a time and because I had no more problematic symptoms I had seen whilst playing). I posted a page back on under what conditions this error seems to occur under. As for outdated mods, I know that at least according to civs internal loader, non of my mods are declared in need of updating. I also know this doesn't mean I do not have non updated mods, but I assume once I run stopwatch logs (I assume I can find instructions on how to run these on here) that will tell me which mod is problematic and ergo, outdated.
Honestly, I am quite alarmed by the logs, because they seem to be telling me I am having A LOT of errors before I even run E&D even though whatever these errors represent is not materialising in a noticeable gameplay error... Ultimately I can do the run singlular mods untill I find the problematic one, but that is hardly a joyful process with me running 30 or so mods currently and civ not booting particularly fast. Thanks again for your help (even if it has given me more apparent problems than I started with XD)
Edit: By stopwatch logs do you mean the sort that log all PC processes or is there something civ specific I should be looking for?
Also, if I need to provide other logs for you or other details that are exhaustively specific, I am afraid I am away from the relevant pc for some time. Apologies for asking for help and then being unable to follow up on it.
Edit 2: I have just visited JFD's discord and I may well have found my culprit. Perhaps it is that I think I am using Hungary who are incompatible. When I have access again, I shall certainly try it without Hungary.
