Instead his powers failed him. He was doubting whether or not he should be Spider-Man. This doubt was causing his powers to randomly fail.

• Superhuman strength, agility, jump, reflexes, stamina, durability, coordination, and balance.
• Wall-climbing on surfaces and ceilings.
• Precognitive spider-sense.
• Genius-level intellect.
• Proficient scientist and engineer.
• Utilizes wrist-mounted web-shooters.
• Accelerated healing.
• Master acrobat.

Instead, his webbing is artificial, created by a chemical of Peter's own making that solidifies slightly when exposed to air, fired by wrist-worn “web-shooters.”

Since his original inception, it has always been something he developed on his own to complement his powerset. As such, he requires web-shooters to shoot webs, because he doesn't have that ability on his own.

In the new movies, they decided to adapt it much more faithfully to the comicbooks so they used mechanical webshooters as well. I personally like the mechanical webshooters better just because I grew up with them in the old comics and cartoons.

And how are they made? Spider webs are notoriously strong, with spider silk reported as having a tensile strength of up to 1.75 gigapascals (GPa), or just over 178 kilograms per square millimeter in cross-section (to save U.S. readers from looking it up, 178 kilograms comes to 392.4 pounds).

Genetically imprinted with spider DNA, Miguel has superhuman strength (lifting 10 tons under optimal conditions), speed, stamina, reflexes and agility, and enhanced durability. He can jump up to 30 feet. He has enlarged canine teeth (fangs) which can secrete paralyzing venom.

Gwen possesses a pair of wrist-mounted mechanical web-shooters gifted to her by the retired crime-fighter-turned-billionaire-mogul, , Janet Van Dyne, AKA The Wasp.

The main conflict of Spider-Man: Across the Spider-Verse centers around Miles Morales' refusal to experience the same fate of every other Spider-Man, which leads Miguel O'Hara a.k.a. Spider-Man 2099 to chase down Miles in order to keep the multiverse safe from collapse.

Perhaps the biggest changes to his power set are his talons, venomous fangs, and organic webbing, however, as Miguel's produces spider-like silk naturally from his wrists, rather than having made synthetic webbing like other Spider-Man variants.

While most Spider-Man adaptations retain the iconic mechanical web-shooters, Sam Raimi's Spider-Man trilogy opted to give the character played by Tobey Maguire organic web-shooters, providing the power to shoot web from his body but otherwise functioning almost identically to the comic iteration's devices.
