Execution timeout problem when trying to add new field I've been having some problems since I've updated yesterday to craftcms v3.4 (was 3.3). When I try to add a new field via the admin, it takes an enormous amount of time (almost 5min, had to raise the nginx timeout and php execution timeout) on my local dev setup. 
Amount of fields I have are pretty minimal for now. 
I'm running following craft plugins:

"aelvan/imager": "^2.3",
"barrelstrength/sprout-fields": "^3.5",
"clubstudioltd/craft-asset-rev": "^6.0",
"craftcms/cms": "^3.0.0",
"craftcms/redactor": "^2.4",
"mikestecker/craft-videoembedder": "^1.1",
"sebastianlenz/linkfield": "^1.0",
"verbb/navigation": "^1.2",
"verbb/super-table": "^2.3",
"vlucas/phpdotenv": "^3.4.0"


Does anyone have an idea what the problem could be? Doesn't feel very manageable at the moment.

Thanks in advance.
Some common steps to find the culprit.


Always work in dev mode 
Enable Debug Tool­bar or read the brief tutorial by nystudio107
Disable all the custom plugins one-by-one.
Once development is done, switch to production mode and disable log.
Adjust Mysql and Server minimum configuration based on your site load.
There is no need to use multiple cache strategy.
Activate useful admin dashboard widget only.
On the entries page, activate the most useful Table Columns only. 

Check system report information in the dashboard, make sure all the suggested requirements are fulfilled.
