Your latest output_log.txt reports the same "corrupted ZIP" error before crashing as previously. So it seems most likely that the first crash after starting with a new character caused a corruption in your savegame file. Pillars does seem to scan savegame files on startup so an invalid one can cause a crash on the intro screen.
My suggestion would be to go to your savegames folder - create a subfolder in that (called "Backup" say) and to move the most recent savegame to that. Then try restarting PoE. If problems continue, move the next most recent savegame to Backup and continue until you reach one that works. That will mean losing in-game progress but if you have been saving often, hopefully not too much.
If you want to confirm that a moved savegame is the cause, you can move it from Backup to the savegame folder and see if the problems return.
Ok, I did what you instructed. I put the most recent save in the "Backup" folder and loaded the save prior to that....voila...it worked. so, I immediately went to an inn, rested my party, and then saved the game. As an experiment tried to load the recent save (at the inn). It crashed my PC. So, I rebooted, moved the most recent save to the "backup" folder and tried to load the previous save...it crashed my PC. <sigh> I just don't get it.
