Crashing to desktop with specific Character

So the last 2 days I have been experiencing the weirdest problems ... starting with error 2002 and 90002 randomly even after not changing anything at all.

Now these don't appear anymore and I can (sometimes) even log into the game with my character however the game just crashes in loading screen or after 2-10 seconds being online and walking around. There's no error message.

Funny enough I tried playing on a free trial account without any problems whatsoever for an hour just now on the same PC with the same settings and everything.

Tried crating a new character on another realm (Crystal) and there it crashes in character creation.

Absolutely clueless what to do ...

Good afternoon and thank you for posting in the Final Fantasy XIV Technical Support Forums

How long have you been experiencing this issue? In addition what have you tried to alleviate the issue?

Just answering because I solved the issue after pretty much attempting everything else.
For me it just was to install the game to the standard location on the C drive ... don't have much space there sadly but at least it works.
