Can't open a specific place

I can’t open a .rbxl file. I get this iostream stream error

files that I saved myself can be opened but this file I got from someone who made a map for me. my specs are GTX 1650, Ryzen 5 and 16GB RAM.
Beta features I got turned on are the simpler ones such as Dragger QoL, Face Capture, Improved Constraint Tool, Improved UIStrokes, Live Animation Creator, New Studio Camera Controls, UIDragDetectors and Video Uploads.

Expected behavior

if worked correctly, it would open the map

SOLVED:
I had to rename the file for some strange reason and it works now
