It seems that when I launch Open blocks (open mods lib and Open blocks are updated to the latest snapshots) it gives me a "unable to determine capabilities" error then crashes idk why :(

@Ianaver looks like I'm too harsh for old PCs - this should be log, not crash. I will fix it later today, but you can just disable it by setting value of activate_gl_capabilities_hook to false in config/OpenModsLibCore.json

@Julia122 No. This crash was already reported multiple times and it's caused by starting mods for 1.6.4 in 1.7.10. Use snapshots.

Fixed in OpenModsLib snapshot 252

thank you so much!! :)
