Hello, I am ready to reward someone who helps me with an electrum wallet. In general, I found my file on an old laptop with an electrum folder, I have several files and one of them is my wallet.dat 24kb in size, it has a lot of addresses with my balance, but more on that later, I have blockchain_headers files with a size of 46 kilobytes. config 1 kb, daemon and recent servers. My mistake is that on the old laptop everything worked fine by opening wallet dat and displaying my bitcoins, but in the latest version when opening wallet.dat it gives errors when opening File
"electrum\gui\qt\main_window.py", line 507 , in load_wallet
   File "electrum\util.py", line 469, in do_profile
   File "electrum\wallet.py", line 3324, in try_detecting_internal_addresses_corruption
   File "electrum\wallet.py", line 3329, in check_address_for_corruption

and when sending a transaction:
the error Script failed an OP_EQUALVERIFY operation

and I can’t withdraw bitcoins at all, I tried restoring via private keys, but generally gives out other addresses with a balance of 0, I tried to restore using a seed phrase but gives me wallets without a balance and with old ones transactions, that is, the balance is 0, and when I enter wallet dat and with these errors, electrum shows my old normal balance, but I can’t withdraw bitcoins because of these errors, the Internet connection is stable, can I somehow restore my wallet by deciding those line errors (removing those errors with python) ? Will additional files to the wallet blockchain headers help me or others that I have? If someone helps me, I'm ready to reward him!
additional contact with me telegram @m1kmrt and my mail woycemisha@gmail.com you can write me in private messages and here on the forum!

Perhaps you could try uninstalling the latest version of Electrum and install an older version instead? You mentioned the "old laptop"? Do you still have access to it? Or perhaps you can remember the version of Electrum you used on your old laptop?
