Hmm, but the bug attachment says the program crashes some time after running,
not that it fails to open or crashes on start.

To test per the original report ("after some time"), can you try opening
different PDFs and scrolling through, navigating back and forth and so?

Just looking quickly, I see two crashes with 2.5.315.0 and wine-5.1, one looks
unrelated and another sure if could is related to the original (might differ
because I'm on MacOS).

I opened this PDF using the open from URL option:
https://www.adobe.com/content/dam/acom/en/devnet/actionscript/articles/PLRM.pdf

While navigating after scrolling a few hundred pages, I get:

PDFXCview.exe(37619,0x7c469080) malloc: can't allocate region

or after mousing over some of the menus, I get this:
