--- Comment #3 from ritalat@fastmail.com --- Created attachment 70382 --> https://bugs.winehq.org/attachment.cgi?id=70382 updated arch packages from july 21
The issues start with arch packages from July 21. I've attached the list of packages that were upgraded on my system between the 20th and 21st.
The wine-staging update seems to be a red herring as updating it to 6.13 but keeping all other packages from the 20th does not cause any issues.
