@wargio
Just found a method to replicate with public accessible project, libbotan. I tried libbotan 2 with gcc 7.5, and libbotan 3 with gcc 11, both crashed when using Cutter-v2.3.4-Linux-x86_64.AppImage. However, if build the cutter from source, then it does not crash.

wget https://botan.randombit.net/releases/Botan-2.19.5.tar.xz
tar xf Botan-2.19.5.tar.xz
cd Botan-2.19.5
./configure.py --disable-shared --cpu=x86_64 --os=linux --cc=gcc --with-endian=little --with-os-features=posix1 --with-debug-info --prefix=/path/to/botan/installation
make -j$(nproc)

No need to make install, just open the .a file with Cutter.

probably is a bug due something that has changed.
