I cant use 0.8.20+ due to some errors how can i use an older version of the erc20 contract from open zeppelin

The most recent version of the library requires ^0.8.20 as of now. The alternative is to install the previous v4. You can do it in Remix by suffixing your imports with "@v4.9.3" (the latest v4) as in:

import "@openzeppelin/contracts@v4.9.3/access/Ownable.sol";

So why not handle these errors instead of trying to switch back to an older version, and ending up with a bunch of other errors?

@Aarav You can post the errors here, it's better to solve them and go with the default version.

:heavy_plus_sign: to other comments. If you can solve the issues and move to 0.8.20, you should.

I'd suggest using 4.9.3 only when strictly needed from now on unless you already have a project with a version dependency tied to 4.x
