--- Comment #1 from algebro@tuta.io --- Created attachment 72203 --> https://bugs.winehq.org/attachment.cgi?id=72203 Decompiled code near crash
Poking around in a debugger/Ghidra, the crash occurs in a function call near some code dealing with shared resources. No idea if it's related, but I believe shared resources are currently only available in proton. I've attached the relevant decompiled code from Vuplex WebView.vuplex in case that's helpful.
