We need an episodic save, or auto save in River Raid due to crashes!

I just played River Raid for the new champion quest in River Rhine, about an hour long of prep work for the boss fight to get food, and all enemies killed at the location. Then I defeated the new champion.

When I set sail on the river, right before I was about to select to go home, the game crashed! After an hour of gameplay and killing the champion.

I know we don't have save function during River Raids to increase the risk for getting killed.

But that does not mean to increase the risk for our game to CRASH!

Please give us something like episodic or auto save during river raids after finishing each location in case of crashes. If we get killed, delete the save. Dying is part of the risk. Our own fault. We die we lose.
But if the game crashes, we then have a point where we can continue without losing all the stuff we have accomplished already. Because crashes are Ubisoft's fault. We should not be punished for them.

I think i found a fix for all the crashes, the problem is the cache folder in document/Assassin's Creed Valhalla folder.

If i delete the cache folder and start the game the game doesnt crash, but while playing the game a new cache folder is generated and gets populated with library files and the game crashes randomly.
but luckily windows allows us to block the folder from being accessed by the game, thus the game cant generate any folders inside the document/Assassin's Creed Valhalla folder.

Steps:
delete all folders inside document/Assassin's Creed Valhalla folder except for the ACValhalla configuration file.
Open windows defender security center
click on virus & threat protection
under virus & threat protection settings click manage settings
scroll down until you see controlled folder access and click manage controlled folder access
enable it
click on protected folders
add document/Assassin's Creed Valhalla to the list
start the game, if you get a notification that acvalhalla.exe app is blocked from accessing the folder, you done it right

hopefully this works for you.

Update:
Since i posted this, i didn't have any crashes. However the game attemped to make a new folder (Assassin's Creed Valhalla folder) somewhere else, in my case it was in the same drive where the game was installed.
Follow the same steps, i am 100% sure that the cache folder is the culprit, i went from crashes every minute to no crashes, i even tried to crash the game, like alt tabbing a lot, leaving the game in background, and still the game wont crash.
I am also running the game as admin, with windows 8 compatibility mode and disable fullscreen optimization enabled + i run the game manually from the root folder where the game.exe file is located.

Edit -  ignore the steps in my post, and just run the game in fullscreen, and don't use borderless in the game settings
