Did you check the error log?
Based on the code, when uninstalling its changes the .htaccess in admin/ and root folder.

lscache-opencart/3.0/upload/admin/controller/extension/module/lscache.php

Line 571 in dafae6a

private function clearHtaccess()

I don't have .htaccess file on /admin folder. Only have it in root folder.
I compare the rewrite rule with the one that before uninstall the cache extension.
I found that it only remove the follow rule in the /.htaccess file:

My cache extension is the newest edition download from github of lscache-opencart3.0-latest.ocmod.zip
It seems that the extension had update by WuhuaChen two month ago.
Besides，I am using Journal V3.0.46 theme for opencart.
I think that it may not the problem of .htaccess file.
My frontend is working correctly,but just no response from the backend.(http 500 error -blank page)
