@squad_z Hey there, I'm sorry to hear you're experiencing these crashes! If you haven't already, please have a look at our Basic PC Troubleshooting guide?
Please also make sure your game and launcher are installed on the same driver, as having them on separate drives can cause issues like this.
If this does not solve your issue, I'd recommend that you reach out to our Support Team via our Support Website, Twitter DMs, or Facebook PMS with copies of your MSINFO and DXDiag, as well as a summary of your issue. Once received, our teams will be able to look into this further with you.
If you're contacting through Social Media, please make sure to also include the username and email address associated with your Ubisoft account. Our teams there will have to link your account before you're able to upload your files. Thank you!
