Is it just me, or is it anytime you get a flat when your riding trials theres no way to patch the tire.
The couple flat tires I’ve had all have been huge gashes 1" to 8" in the tube that are not patchable.
Time to get another tube…

If you take out the valve from the valve stem you can put one tube inside the other for double thickness, then replace the valve.
Topologically speaking, that is.
