Mesen2 is crashing on Fedora 43

On Fedora 42, latest release of Mesen - Mesen_2.1.1_Linux_x64.zip , was working correctly. After upgrading to Fedora 43 (not a clean installation, but in place upgrade), I noticed, that running Mesen is crashing with very terse error message:

terminate called after throwing an instance of 'std::bad_cast'
  what():  std::bad_cast
Aborted                    (core dumped) ./Mesen

I tried using gdb and looking into coredump, but came up with nothing.

Tried bulding source code inside a flatpak, just to make sure it might be related to some recent libraries, but it crashes with similar error message:

Segmentation fault (core dumped)

This application is built on dotnet , and source code is available. I wonder if someone could help me to debug this issue? Or just point into right direction how to correctly debug this situation.

Same application is working without issues on Linux Mint 22 (latest release with all updates).

Here’s a build for F42+ that works for me:

Thank you for quick response. Your build led me in the right direction. I had to disable AOT in build options for application to work without crashing.
