jemasoniii: I was about to come here and post the same exact thing, but I think I might have finally fixed this issue after trying every thing else. Here is what I did:
1) Close GOG Galaxy (close it from the task task manager to make sure it's closed)
2) Open 'C:\Program Files (x86)\GOG Galaxy\plugins' or wherever you've got GOG installed and delete everything here. 3) Open `C:\Users\xxxxxxx\AppData\Local\GOG.com\Galaxy\plugins\installed` or wherever your appdata is. Delete everything here as well.
4) Restart Galaxy and wait for it to redownload the plugins.
I did this a couple of hours ago, and no plugin crashes since then, where it would normally crash a minute after restarting. Hope this helps.
That solved it for me. Point #2 no longer applies though - the downloaded and installed plugins are both under appdata now.
