Giant stretched-out black triangles glitch

Hello! I'm deving a mod called Mirage. Recently I've switched to using VertexBuffers to render fake structures but I came across this bug whenever I enable shaders: Is there anyway I can change my code to work with yours?

I initialize the VertexBuffers with this method whenever I rightclick on the projector block:

public void initBuffer(BlockPos projectorPos) {

        MatrixStack matrices = new MatrixStack();

        this.mirageStateWOEntities.forEach((key,block)->{
            matrices.push();
            BlockPos fakeBlockPos = BlockPos.fromLong(key);
            BlockPos relativePos = fakeBlockPos.subtract(projectorPos);
            matrices.translate(relativePos.getX(),relativePos.getY(),relativePos.getZ());

            RenderLayer renderLayer = RenderLayers.getEntityBlockLayer(block.blockState,true);

            blockRenderManager.renderBlock(block.blockState,fakeBlockPos,world,matrices,

                    this.mirageBufferStorage.getLayerBuffer(renderLayer),//over here

                    true,random);

            matrices.pop();
        });
        
        this.mirageBufferStorage.uploadBufferBuildersToVertexBuffers();

    }

public void initBuffer(BlockPos projectorPos) {

        MatrixStack matrices = new MatrixStack();

        this.mirageStateWOEntities.forEach((key,block)->{
            matrices.push();
            BlockPos fakeBlockPos = BlockPos.fromLong(key);
            BlockPos relativePos = fakeBlockPos.subtract(projectorPos);
            matrices.translate(relativePos.getX(),relativePos.getY(),relativePos.getZ());

            RenderLayer renderLayer = RenderLayers.getEntityBlockLayer(block.blockState,true);

            blockRenderManager.renderBlock(block.blockState,fakeBlockPos,world,matrices,

                    this.mirageBufferStorage.getLayerBuffer(renderLayer),//over here

                    true,random);

            matrices.pop();
        });
        
        this.mirageBufferStorage.uploadBufferBuildersToVertexBuffers();

    }

MirageBufferStorage:

public void uploadBufferBuildersToVertexBuffers() {
        this.mirageLayerBuffers.forEach((renderLayer,bufferBuilder)->{
            if(bufferBuilder.isBuilding()){
                bufferBuilder.end();
                this.mirageVertexBuffers.get(renderLayer).upload(bufferBuilder);
            }
        });
    }

public void uploadBufferBuildersToVertexBuffers() {
        this.mirageLayerBuffers.forEach((renderLayer,bufferBuilder)->{
            if(bufferBuilder.isBuilding()){
                bufferBuilder.end();
                this.mirageVertexBuffers.get(renderLayer).upload(bufferBuilder);
            }
        });
    }

Then I render the VertexBuffers in my Projector block's BER:

public void render(BlockPos projectorPos,float tickDelta, MatrixStack matrices, VertexConsumerProvider vertexConsumers, int light, int overlay){
        MatrixStack matrixStack = RenderSystem.getModelViewStack();
        matrixStack.push();
        matrixStack.multiplyPositionMatrix(matrices.peek().getPositionMatrix());

        this.mirageBufferStorage.mirageVertexBuffers.forEach((renderLayer,vertexBuffer)->{
            renderLayer.startDrawing();
            vertexBuffer.setShader(matrixStack.peek().getPositionMatrix(), RenderSystem.getProjectionMatrix(),RenderSystem.getShader());
            renderLayer.endDrawing();

        });

        matrixStack.pop();

public void render(BlockPos projectorPos,float tickDelta, MatrixStack matrices, VertexConsumerProvider vertexConsumers, int light, int overlay){
        MatrixStack matrixStack = RenderSystem.getModelViewStack();
        matrixStack.push();
        matrixStack.multiplyPositionMatrix(matrices.peek().getPositionMatrix());

        this.mirageBufferStorage.mirageVertexBuffers.forEach((renderLayer,vertexBuffer)->{
            renderLayer.startDrawing();
            vertexBuffer.setShader(matrixStack.peek().getPositionMatrix(), RenderSystem.getProjectionMatrix(),RenderSystem.getShader());
            renderLayer.endDrawing();

        });

        matrixStack.pop();

I heard you guys are using custom vertex formats is that right? embeddedt says it might have something to do with it
