Bug ID: 56814
           Summary: "Lossless Scaling" program crashes on launch
           Product: Wine
           Version: 9.10
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

3 backtraces for attempts to launch the program with wine.

Ubuntu 22.04, x86-64bit AMD.

Running wine 9.10, the program fails to launch, outputting the first part
(attached). With the 9.10 Wine Mono msi installed via "wine uninstaller", it
still fails to launch, outputting the second part. The outputs also mention
dotnet48, so I installed this with winetricks --force -q dotnet48, however this
gave the third output. This was reproduced identically in clean 64 and 32 bit
wineprefixes.

Background on the program:

Lossless scaling is a tool for real-time GPU driven resolution up-scaling and
frame interpolation of other programs. As an example, I use it on Windows to
bring the game "Celeste", which is locked to 60fps, up to 165fps graphically
without the subtle physics alterations that existing fps increase mods result
in. No such tools yet exist natively for Linux, and I am not aware of any
others on Windows.

Looks like bug 52092. Does the patch there help?

Yes, I am talking about that linked app. I rebuilt wine with the linked patch,
and the backtrace was exactly the same. I used make -B so the patch was
definitely applied.

I also saw that that one you linked had
"Windows.Foundation.UniversalApiContract, Version=7.0.0.0", in the backtrace,
whereas mine mentions Version=8.0.0.0, so I modified the patch to instead add
version 8, but this also resulted in the same backtrace. I also tried with
every combination of (via winecfg): Windows 7, 8, 10 and 11; and: without any
patch, with the linked patch, and with the linked patch modified to version "8"
instead of version "7". All of these produced the exact same backtrace, all
mentioning "Version 8.0.0.0" at that point regardless of windows version or
patch.
