dyncss breaks extension configuration in TYPO3 9.5

[kfinke]

Since an update from TYPO3 7.6 to 9.5 the dyncss-extension breaks the extension configuration, so configuration of any extension can be done only by deactivating dyncss.

I get an ajax-error, here is the first part of the error shown:

Error Call to a member function setAndSaveSessionData() on null

in /html/typo3_update/typo3_src-9.5.15/typo3/sysext/core/Classes/Messaging/FlashMessageQueue.php line 151

• @param FlashMessage[] $flashMessages */ protected function storeFlashMessagesInSession(array $flashMessages = null) { $this->getUserByContext()->setAndSaveSessionData($this->identifier, $flashMessages);

Which version of dyncss do you use? Did you tried the Github-Master?

[kfinke]

Yes, I us the github-master version 0.8.3

the extension config is not critical for the usage, but we will take a look into it. may take a couple of days.

[kfinke]

Sorry, I had the same version number (0.8.3), but obviously another version of dyncss. I downloaded the version from github directly now - the error is gone, I can open the extension configuration now.
