Samsung S23 Plus WIFI/BLUETOOTH ISSUES after ONE UI update 6.1

Bought a new S23 plus about 4-5 months ago (28.april). Had no issues with the phone until One UI version 6.1. 

- After updating i started loosing wifi and Bluetooth, like not able to connect at all and no wifi network/devices showing. And wifi i constantly staying in "Turing on.." not finding any nearby WIFI. Had this issue a while now and sometimes it randomly starts working again maybe a few days and then then, suddenly stops working and cant find any wifi networks any more. 

Quite an annoying problem and should not be expected with an "high end" device like this.

- I also have an older S10e that i compared with and it finds the different Wifi networks no problem and the issue is only on my S23. So any router issue can be ruled out. On the S23 its not just home network's but, any wifi. It simply can't detect/register it at all.

Troubleshooting ive already done multiple times include:

- 1. Use the Samsung Members app to diagnose Wi-Fi connectivity issues. Open the Samsung Members app, go to Support and tap 'Phone diagnostics', and select Wi-Fi' to test it. 

Not helpfull at all becuase it doesn't even test anything when there is no wifi signal. Just says all OK. Useless

- 2. Reset the settings. Settings>General management>Reset>Reset Wi-Fi and Bluetooth settings. No difference 

2. Test in Safe Mode. No difference

3. Clearing the cache partition. To get to recovery mode: -Turn off phone ⁃ Once off, hold down volume up and power buttons simultaneously ⁃ When Samsung logo appears, release power button BUT KEEP HOLDING VOLUME UP until the recovery menu appears ⁃ Use volume buttons to navigate down to clear cache. No difference 

- also done a "hard reset" between all these. Holding powerbutton and lower volume, util it shuts off. Which seems to work sometimes. But not every time so i think the phone just randomly decide to work at does times.

- Only thing i havent done is a factory reset of obvious reasons. Which i would like to avoid doing if i possible 

So with all that, im pretty sure this is a software issue the way it just randomly starts working for a while and then stops again. What else can i do to permanently get rid off this issue?

Anyone who can assit me here?
