Error: Cannot write image to ROCCurve.png. Please ensure that proper disk permissions are set.

I ran into the following error while running code I've run monthly for the past 6 months. I have no idea what caused this error or how I should troubleshoot:

NOTE: PROC LOGISTIC is modeling the probability that EVER_120_FLAG='1'.

NOTE: Convergence criterion (GCONV=1E-8) satisfied.

ERROR: Cannot write image to ROCCurve.png. Please ensure that proper disk permissions are set.

See 49421 - A "Cannot write image" error might occur with ODS Graphics and the SAS/GRAPH® Statistical Gr... as a possibility.

Usage Note 49421 does not seem to help here. The .png files are set to be saved to my work directory, and SAS has no issues saving .sas7bdat files there.

Couple of thoughts:

• Restarting my computer resolves the issue. I run the same code and there are no problems.
• The results viewer in SAS turns weird, and has issues displaying other outputs, not just the roc curves.
