Hey,
Are you sure there are no custom changes done to the Sentry module, and all deployment steps finished successfully?
(mainly,bin/magento setup:di:compile and opcache is cleared)

The reason why i ask is that since 4.3.0 the monolog plugin is no longer a preference, but a real plugin.
https://github.com/justbetter/magento2-sentry/pull/184/files#diff-093a1e43a11122404c853506b7ca4f661e18dd4f6557ec3089cad8ceae34a606
Thus it would not extend the LoggerInterface anymore, and it should be impossible for the monolog plugin to be returned from anything.

It seems like what has happened for you is that MonologPlugin has changed, but the di.xml changes have not been processed
