I think I may have found a (temporary? it's yet to break on me) fix! I opened the launcher 'steam_4.1.1.1473368_alteredFiles' file located in the appdata/local/larian etc. cache directory, and it pointed out the file DWrite.dll in the game's bin folder was apparently the altered file. I moved it elsewhere and the error message no longer shows up and an issue I was having with a CTD bug disappeared.
Dunno if this method might help others find what their specific problems are but thought I'd report my findings.
