some of the crashes-dumps are because of Rosalina, if the crashes for you are frequent try switching to Luma-Legacy this is basicly 8.0 w/o Rosalina (this means however you need to move back to Home Brew Launcher + an updated Payload. and i believe renaming the 11.4 one for 11.5 works for N3DS's only. ) you "Can" disable the ARM11 Exceptions but if you were to ever report a bug it would be dismissed if it occurred while these Exception handlers were Disabled.
if they are Occurring when not running homebrew OR games then give us more details.
