This line of code:
where
causes this error:
The same line of code on the previous run of this program worked fine (for the last ~3 years) and I have made no change to those functions in a while, I have several similar usage of File.DirData in the program and they all crash now
Of course, the folder "AppData\Roaming\R9_B4J" is still there and since I am creating the file, it is unexpected to get java.io.FileNotFoundException
Any help appreciated!
Additional information: the previous version of this application still runs fine with the same line of code on the same machine, something else must have changed in this version that causes the problem, but while I made a few changes, none were intended to affect file system access. I did use BeyondCompare to compare the file that works and the one that does not and the changes have nothing to do with file or directory access. The app is quite big so I am reluctant to post it in it's entirety.
