My new laptop won't install Windows 11 Insider Preview Feature Update 26220.7535

Good evening, everyone. It's been days since I've been able to relax, it's been one offset after another. I'm still reeling from seeing my old laptop die last week. I'm typing now on a new laptop, and exhausted after reinstalling everything. I'm having trouble installing the latest build listed above, and I can't access Windows Update Troubleshooter without that malfunctioning either. I've tried several remedies but none of them have worked. I get errors saying the partition isn't big enough to accommodate this build, when I have plenty of space to spare on this laptop. I understand others are experiencing the same frustration with this. I do not want to do a fresh install and start from point zero again, I've been losing enough sleep at night. I tried looking for a manual download on the Microsoft Update Catalog, but I found nothing yet to match this upgrade. PLEASE help me get this installed.
