Important:
Only works if your current Unity editor matches the .vrcw Unity ver.
The Tool will tell u which Version was used, just downgrade ur SDK then.
The script scans the .vrcw and tells you what version of Unity it was made in.
22f2-DWR works in 22f1 too.

Low Risk of getting banned, but still be careful, use Alt Accs for Uploads.
DONT upload ripped Worlds to Public Spaces, Speedrun Ban.

After step 3, don't click Build & Publish again. That undoes the swap.

Note:
When Packing with LZMA/LZ4, there can be a "processing" time, meaning it can take some time for you to be able to join the world, sometimes 5-30minutes, or maybe even more.
When using LZ4Runtime, "processing" time is near instant.
(No compressor needed for LZ4Runtime, world also needs to be less than 1.5GB ideally because LZ4Runtime compression is not as strong as LZMA)
