Trespasser insta-crash

I was really looking forward to this. 😞

Here's what I've done, and none of it works. I am a PC user.

• Removed mods. Went to War Table, accepted mission, ventured forth.
• Loading screen started then CTD.
• Went back to war table, accepted mission, wandered Hinterlands then Crestwood (btw, once I engaged an enemy, my party continued in battle mode  even though there were no enemies or even other beings in the vicinity. I had to manually disengage and quickly bring up the map so I could travel, otherwise everybody would enter battle mode again. I had to try multiple times because the timing had to be just so), returned to Skyhold and tried to fast travel to Halamshiral.
• Loading screen started then CTD.
• Made sure I was in beige pj's. back to war table to try again.
• Loading screen started then CTD.
• verified no trials selected and changed horse from giant nug to Fereldan Forder, back to war table.
• Loading screen started then CTD.
• all 'lunge and slash' abilities disabled for all warriors, back to war table.
• Loading screen started then CTD.
• switched to windowed full screen with no borders, back to war table.
• Loading screen started then CTD.
• changed to regular window, back to war table.
• Loading screen started then CTD.
• Deleted Patch folder, ran repair, adjusted version number in package.mft file, back to war table.
• Loading screen started then CTD.

I don't know of anything else to try.
