Strange controller behavior after experimenting

Hello, fellow VESC people!

I recently installed a new motor on my electric bike. Like most Chinese motors, it came without any documentation. The seller advertised it as 3000 - 3500 watts, up to 72 volts and 45 mm magnets.
Since there is no documentation, I tried to find the right settings experimentally.
My equipment:
1) VESC Spintend Ubox 100V 150A controller (FW: 6.05, no hw limits);
2) 48V battery (13s12p, 21700 cells).
I gradually increased the battery current with 2A steps and checked how everything works. The phase current limit was set to 240A and did not change during the tests. Regenerative braking was enabled and the current was limited to -10A of battery current. Braking worked well.
Eventually, I set the current to 62A and began to accelerate. The motor made a loud clicking sound (more like bang sound). VESC does not trow any error. I immediately stopped and reduced the current back to 60A. With such current everything works fine again. The motor does not make any extraneous sounds. But regenerative braking has stopped working completely. I tried to reduce the battery current, increase the braking current, but nothing helps. I do not understand. This is very strange. If the MOSFETs or motor windings are damaged, then nothing would work. But everything works fine, except for regenerative braking. If anyone understands what is happening, please help me.

P.S. Nevermind, problem solved.
