Switching from Delphi 10.4 to 11.3 Community Edition, I got a Access Violation on command TMSFMXDirectoryTreeView.LoadDrives(False) on 64 bit run after successful compile. This does not happen using 32 bit run on 11.3. This was not an issue on Delphi 10.4 with 32 or 64 bit compiles.
Run the Sample for TreeView Directory. I have more than one app using this control feature. Must compile with 64 bit option to see error when sample runs.
Thanks for the feedback, we have traced and solved this issue. Next version will address this.
