The new ImmediatelyFast Version from June 1st just completly messed up all of my shaders and I as soon as I disabled this mod / downgraded to the old version, everything was fine.

Closed due to lack of information/response

There is no ImmediatelyFast version from June 1st. Upload the game log and affected shaderpack

The user is referring to the difference of v1.9.5+1.21.5 and v1.9.4+1.21.5 as part of Fabulously Optimized 9.0.0-beta.3 and 9.0.0-beta.4, respectively.

Shaders

• BSL v8.4.01.2
• MakeUp-UltraFast-9.1e
• photon v1.1

(did not get any logs from the user yet)

Can't reproduce the issue. BSL shaders seem to work fine with the latest ImmediatelyFast release:
