Converting an output to Mesh output results in broken shader compilation and error

Steps to reproduce:

1. Import learning templates
2. Open MultiStripSingleBurst VFX
3. Convert output to URP/HDRP (Un)Lit Mesh

Actual results: Shader compilation breaks and shader errors are thrown

Reproducible with versions:  6000.0.33f1, 6000.2.0a5

Not reproducible with versions: n/a

Can’t test with versions: n/a

Tested on (OS): Windows

Notes:

• i didn't check other streams to confirm if it is a regression
• seems to happen with Mesh Unlit/Lit Output only, tested converting to quad, point and couldnt repro
