*The modpack is unmodified, it is clean install.

You didn't allocate enough RAM and it ran out while loading. The recommendation is 10 GB. If you're using curseforge, it only allocates 4 by default, so you'll need to manually set it to allocate more.

Toastr is correct.

this combination of lines in the report is what tells us this.
com.google.common.util.concurrent.ExecutionError: java.lang.OutOfMemoryError: GC overhead limit exceeded
Memory: 526810264 bytes (502 MB) / 4194304000 bytes (4000 MB) up to 4194304000 bytes (4000 MB)

as noted, allocate atleast 8GB to the game in your launcher, 10GB is the advised amount for smooth play.
