Bluetooth Share crashes, onscreen keyb stutters

[Hobbes2099]

A few weeks ago my Z4 announced Bluetooth Share had crashed. It took me about a minute to realize that the Bluetooth icon on the right side of the notification bar had disappeared and that my physical keyboard stopped working. It would recognize every other keystroke every few seconds.

Searching Google, I found answers dating back to 2014 recommending me to clear the app's cache.
That plus cold rebooting the tablet.

That worked perfectly fine until last night when I got the same problem.
Now I can't clear cache, I can only press Clear Data. Every time I warm reboot, the app remains crashed. And every time I cold reboot, Bluetooth works fine for about 90 seconds and then I get the same crash notification.

Any suggestions or recommendations?
I'd rather not wipe my device but I will if it has helped anyone before.

Also, when Bluetooth Share crashes, the onscreen keyboard stutters every few seconds. Both, the Xperia keyboard and the SwiftKey keyboard freeze every few keystrokes.

So an interesting thing happened.
I took out the SIM I have in the tablet because I thought it was the SD card.
Tablet reboots and now the Bluetooth Share app took about 20 minutes to crash.

I've read somewhere that for this type of error, I should to clear the entire device's cache and not the individual app.
There's the "Cached data" that you can find in the Settings > Apps.
I tried this; it went down from 1.91GB to 3.12MB.
I tried rebooting again by removing the SIM.
the Bluetooth Crash was almost immediate after the tablet finished booting.

I guess I'll try wiping the device tonight.
