I have the 5.0 uconnect. This literally just started yesterday when I went to turn car on to leave work. It never passed the start up safety screen. I do plug a charger in sometimes but it is not plugged in. I started researching more and did actually pull the f80 out and it did not resolve the issue.Welcome to the forum. You have the Uconnect 5.0 or Uconnect 8.4 radio?
The radio power fuse is F80, but you may be better served if you disconnect, pause & reconnect the neg (-) battery terminal.
Does the radio ever have times when it does get past the start-up screen & works, or is it locked on the start-up screen?

Anything plugged into the underdash diagnostic connector or any accessories added to the electrical system that might be causing interference?
In its current state, it may not take the software update & may need an exchange (replacement) unit or a repair of your unit.
Software is availible at :
Software Update for Uconnect® - Check For UpdatesCheck here to see if your Uconnect® system is due for a software update. Simply enter your vehicle identification number (VIN) to check for any updates.www.driveuconnect.com
A 4-digit anti-theft code is present in every radio & would be necessary to 'activate' a replacement radio. If you do have to get a replacement radio, make sure that you get a proper sales receipt & the security code.
If you repair yours, the security code may have to be re-entered.
See attached TSB (not a recall). Chrysler may be covering part of the replacement cost for certain owners in certain situations.
Did this also just happen? It may be related to the radio issue as the touchscreen does the HVAC functions too.
The yellow front or rear window defrost light? That is an LED & shouldn't 'burn out' like a conventional bulb. View attachment 62336
