Logs or additional context

No response

Has not been reported.

• I made sure this bug hasn't already been reported.

Is on most update to date version.

• I made sure I am using the most up to date fabric/quilt loader and mod version.

Start by reproducing the crash with Debugify on Minecraft 1.21.11, Fabric Loader 0.19.3, and API 0.141.5 while entering a server. Then trace the stack entry at class_757.modifyExpressionValue$eij000$debugify$scaleNearClipDistance and determine which Debugify change triggers the null player reference. Done means entering the server no longer produces this NullPointerException.
