Filter Gallery issue, FG window not opening

Issue when using the Photoshop Filter Gallery. The Filter Gallery window appears to be referencing the initially opened file. Even when attempting to apply filters to files opened later, the gallery window calls up the original file at the top of the screen. Of course, the filter function is applied to the file normally. The problem lies in the fact that when the original file is closed, the gallery window does not open, having lost its reference target. Judging by the fact that previous filter options are still active, this does not appear to be a functional issue but rather an interface error. This issue persisted when using the latest Photoshop versions from 2025-2026 with an RTX 3090 graphics card.
