Invalid Token error when using Fernet(Python)

I'm writing a simple encryption/encoding program using base64 and fernet, but when decrypting fernet keeps raising an Invalid Token error. Here is the code:

from cryptography.fernet import Fernet import base64 as b64,random as rd def encryt(data): key=Fernet.generate_key() data=bytes(data,"utf-8") key2=rd.randint(0,5) for i in range(key2): data=b64.a85encode(data) data=b64.b32hexencode(data) fernet=Fernet(key) encrypted=fernet.encrypt(data) for i in range(key2): encrypted=b64.b32hexencode(encrypted) encrypted=b64.a85encode(encrypted) for i in range(key2): key=b64.b64encode(key) key=b64.a85encode(key) key=b64.b32hexencode(key) final=b64.b85encode(bytes(str(key2),"utf-8")).decode()+"/?\\"+encrypted.decode()+"~`~"+key.decode() return(final) def decrypt(data): a=data.split("/?\\") key2=int(b64.b85decode(bytes(a[0],"utf-8"))) b=a[1].split("~`~") encrypted=bytes(b[0],"utf-8") key=bytes(b[1],"utf-8") for i in range(key2): key=b64.b32hexdecode(key) key=b64.a85decode(key) key=b64.b64decode(key) fernet=Fernet(key) decrypted=fernet.decrypt(encrypted) for i in range(key2): decrypted=b64.a85decode(decrypted) decrypted=b64.b32hexdecode(decrypted) return(decrypted.decode()) q="testtes:1234//te" w=encryt(q) print(w) print(decrypt(w)) 

Hope you guys know how to fix this!

I'm getting

Traceback (most recent call last): File "c:\Users\teech\projects\Wethgan\pyencrypter.py", line 40, in <module> print(decrypt(w)) ^^^^^^^^^^ File "c:\Users\teech\projects\Wethgan\pyencrypter.py", line 32, in decrypt decrypted=fernet.decrypt(encrypted) ^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Python312\Lib\site-packages\cryptography\fernet.py", line 84, in decrypt timestamp, data = Fernet._get_unverified_token_data(token) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Python312\Lib\site-packages\cryptography\fernet.py", line 118, in _get_unverified_token_data raise InvalidToken cryptography.fernet.InvalidToken 

most of the time, but sometimes it just suddenly works.
