Know that you already know about this problem, well, I also wanted to inform you that everything was compatible on 1.17.1, when I updated to 1.18, the Konrkete library became incompatible with Slight Gui Modifications mod.
Slight Gui Modifications work without Konrkete on 1.18/1.18.1

I'm happy to say that with latest Konkrete and latest Slight GUI modifications and latest ARRP and latest architectury api updates there is no crash at startup of the game and game starts and for me that really loved Satisfying Screenshots feature of SGM it works great without problem.
But I don't know what happens if you change elements in SGM setting that interfere with konkrete/fancy menu mod and I have no reason to find out. just here to say it's not crashing anymore and Satisfying Screenshots works for me :D

fabric loader v0.13.3 1.18.2
fabric api v0.48.0 1.18.2
slight GUI modification v2.1.0 1.18.2
Konkrete [Fabric] v1.3.3-1 1.18.2
arrp v0.5.7
Architectury v4.1.39 1.18.2

Nice, thank you for telling me! :)
