Stuck on Ardolis when switching dimensions

[Ciaràn]

After beating the first boss, when the game demonstrates (or rather try to on PC...) its fast-loading feature and switching dimensions really fast, I always get stuck on Ardolis (the pirate planet).

When Ardolis loads, not all textures are initially present, and Ratchet just infinitely falls down what should be the ocean but is just an empty void. If I go into the menu and select "Reload to last checkpoint", then the planet is correctly loaded, but it seems that the script does not work anymore, I do no longer switch dimensions and am just stuck free roaming on Ardolis, falling in the water. If I jump just when the loading stops, I can land on the ship where some pirates are shooting at me, but I cannot react, move my camera, hit them, or anything. Just running around.

In this state, I simply cannot go further than the introduction level; although it is not a "crash", the game is not playable.

Technical spec:
CPU - i7-4790
GPU - GTX 1080 (drivers up-to-date)
RAM - 16GB
Game installed on SSD
Exclusive fullscreen, 1920x1080, Graphics settings on "very low"

Same with me. It completely glitched out.

I did the backup save thing they said to do in the Pinned comments. It fixed it for me.

Good idea! I tried to load a previous save, but I was still locked to Ardolis, and ended up having to restart the game from beginning...
Definitely recommend to do some manual saves frequently, just in case.

Also, to avoid this glitch (the new game had the same glitch, but at least I could reload just before the boss), I had to downscale the resolution to 1024x768. The loading still took some time, but at least Ardolis was completely loaded and the script continued as intended.
After this intensive sequence, I was able to set the resolution to 1366x768 which seems comfortable... for now.
