Problem 60638. ICFP2024 009: Lambdaman Crawler-Backfill

The ICFP2024 contest was held June29 thru July 1. The contest consisted of five parts: ICFP Language, Lambdaman maze, Starship flying, 3D - graph programming, and Efficiency - processing complex ICFP message to a numerical value.
The Lambdaman 4 maze is medium size,21x21, L near top left, '.' a cheese bit, # is Wall. Matrix uses Wall=0,L=1,Cheese=2. Encircling Walls are added to all mazes.
The contest goal was to write a minimal size, bytes, expression that moves L, Lambdaman, to eat each cheese bit.
Shown is Lambdaman4 with a best known solution is 348 U/R/D/L commands by completing the lower left before lower right. This challenge uses a Crawler-Backfill method thus optimal solutions not found but big puzzles can be completed quickly if paths are width==1 and there are no loops.
This challenge is to solve multiple Lamdaman mazes by eating all the cheese via a char path of UDLR, with a program smaller than the template. The template implements a crawler-backfill This maze has no loops but multiple cul-de-sacs. Fill smallest branch first to minimize total length. The challenge is to make a smaller crawler.
