| I don't know what really happened but after I get disappointed and closed the x32dbg suddenly find Unpacked.exe and it was an easy xor and find the password.
s1 = b"E2*2{0\"z"
flag = ""
for i in s1:
flag += chr(i ^ s1[0])
print(flag)
flag = ""
for i in s2:
flag += chr(i ^ s2[0])
print(flag) |

from pwn import xor
ct = "822="
val = 0x53
print(xor(ct, val)) |
