Minecraft ingame shaders don't appear?

I downloaded a SEUS shader and everything worked fine, then I went into minecraft and wanted my shader to be pulled into the bar and yes it just didn't show up, I tried it 20 times

Download the latest version.

SEUS in particular has some problems with AMD graphics cards. Mine radio. Not at all.

Furthermore: If you play on Bedrock, SEUS does not work because it is no longer updated.
