1995 Lexus LS 400 Timing belt replacement trigger crankshaf

After I replaced the timing belt, water pump, and thermostat my engine light came on. When I drove the car the engine lost power and it would misfire when I accelerated. When the scan test was run it gave the code P0335. I replaced the crankshaft position sensor right away and the sensor failed almost instantly. At this point I have replaced the sensor about 4 times and each has not resolved the problem. My mechanic made adjustments to the "star" where the belt is placed and that helped the car gain some of its power back, but still it didn't help in having the fail code from coming back. At this point I'm at a lost. Anyone can give me an answer?
Do you
have the same problem?

That pretty much tells you that's not the problem. There is likely an issue with the job you performed. It may still be out of time or the wiring may have been damaged.
The 4.0 is an interference engine so if the engine was rotated when out of time, it will bend numerous valves in the engine. This may have been a very expensive learning experience for you. I suggest you let a knowledgeable tech look at it.
