That's because the latest XAMPP use MariaDB and MYSQL Workbench is using MYSQL Database, so they are not fully compatible, raising that error for example.You can try to downgrade to some of the previous XAMPP versions.

blocks|key|1942153|text|首先，找到安装Xampp的目录。在linux中，您只需在终端中键入以下内容：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1942154|whereis+xampp|offset|length|style|CODE|1942155|在我的例子中(顺便说一下，我使用arch，jk)它位于/opt/lampp/bin。如果您使用的是windows，您可能会发现它位于不同的位置，如C:\Program+\xampp\bin中|1942156|接下来，找到文件mysql_upgrade并以管理员或sudo的身份执行它。如果您使用的是Linux：cd+/opt/lampp/bin，那么sudo+./mysql_upgrade|1942157|根据MySQL文档：|1942158|每次升级MySQL时，都应该执行mysql_upgrade，这会查找与升级的MySQL服务器不兼容的地方:它会升级mysql模式中的系统表，以便您可以利用可能添加的新权限或功能。它升级了性能架构、INFORMATION_SCHEMA和sys架构。它检查用户架构。|blockquote|1942159|所以我认为mysql_upgrade应该解决这个问题。以前对我起过作用。|1942160|这里有更多关于mysql_upgrade的信息：|1942161|升级-检查和升级MySQL表|1942162|entityMap|0|LINK|mutability|MUTABLE|url|https://dev.mysql.com/doc/refman/8.0/en/mysql-upgrade.html^0|0|0|D|0|0|1F|H|1Z|K|0|0|0|0|0|0|E|0|0^^$0|@$1|2|3|4|5|6|7|14|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|15|8|@$D|16|E|17|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|18|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|19|8|@$D|1A|E|1B|F|G]|$D|1C|E|1D|F|G]]|9|@]|A|$]]|$1|L|3|M|5|6|7|1E|8|@]|9|@]|A|$]]|$1|N|3|O|5|P|7|1F|8|@]|9|@]|A|$]]|$1|Q|3|R|5|6|7|1G|8|@]|9|@]|A|$]]|$1|S|3|T|5|6|7|1H|8|@]|9|@]|A|$]]|$1|U|3|V|5|6|7|1I|8|@]|9|@$D|1J|E|1K|1|1L]]|A|$]]|$1|W|3|-4|5|6|7|1M|8|@]|9|@]|A|$]]]|X|$Y|$5|Z|10|11|A|$12|13]]]]

First, locate the directory of which Xampp is installed at.
In linux you can just type this in a terminal:
<code>whereis xampp</code>
In my case (btw I use arch, jk) it was located at /opt/lampp/bin . If you're using windows, you may find it under a different location, like in C:\Program Files\xampp\bin
Next, locate the file mysql_upgrade and execute it as an administrator or a sudo.
If you're using Linux:
<code>cd /opt/lampp/bin</code> then <code>sudo ./mysql_upgrade</code>
According to MySQL documentation:
<blockquote>
Each time you upgrade MySQL, you should execute mysql_upgrade, which
looks for incompatibilities with the upgraded MySQL server: It
upgrades the system tables in the mysql schema so that you can take
advantage of new privileges or capabilities that might have been
added. It upgrades the Performance Schema, INFORMATION_SCHEMA, and sys
schema. It examines user schemas.
</blockquote>
So I believe mysql_upgrade should resolve the problem. It worked for me before.

I did have this problem today, the reason is:
<pre><code>Error Code: 1356 View 'test.xyz' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them
</code></pre>
After dropping those view (actually those views) the error was solved.
