Extreme Lag Spikes on 23.18 - Epix Pro

Hi, so my watch (Garmin Epix Pro Gen 2) was automatically updated to 23.18 yesterday and since the update i'm experiencing extreme lag spikes in the software. Sometimes the watchface takes 20-30 seconds to "wake" up from gesture. Navigating the Settings / UI also lags every 5-10 seconds for about 2-3 full seconds, where the screen just freezes. 

I already rebooted several times, deleted all activity. I tried to do a factory reset, but cant even do one as it shows a notice "Device is fully occupied. Please try again later" 


Does anybody else experienced this issue as well, and if yes, are there any simple fixes i have not thought of?
