I captured this 4 nights ago (on 4/13/2025), but no matter what I do, I can't plate solve it in PixInsight. I am using my local GAIA DR3 database files. My focal length is 840mm and pixel size is 3.76 μm. My GPS coordinates are approximately 86W by 35N.
Astrometry.net solved it in 4 seconds: https://nova.astrometry.net/user_images/12422025#annotated
This link is the full XISF file with my GPS coordinates removed:

What do I need to do in PixInsight to plate solve this? I've tried noise reduction and gradient removal, but nothing works. I captured LRGB and none of them can be plate solved, and I don't know why.

Please check the following items:
The initial center coordinates should be inside the image.
The initial image resolution should be within a factor of 2 from the correct value.
If you use an online star catalog through the VizieR service, consider using the Gaia DR3 catalog with local XPSD databases instead.
If the image has extreme noise levels, bad tracking, or is poorly focused, you may need to adjust some star detection parameters.

** RANSAC: Unable to find a valid set of star pair matches.
*** Error: Unable to find an initial linear transformation.
<* failed *>
*** Error: The image could not be aligned with the reference star field.
Please check the following items:
The initial center coordinates should be inside the image.
The initial image resolution should be within a factor of 2 from the correct value.
If you use an online star catalog through the VizieR service, consider using the Gaia DR3 catalog with local XPSD databases instead.
If the image has extreme noise levels, bad tracking, or is poorly focused, you may need to adjust some star detection parameters.
