Internal storage goes missing and reappears after a few seconds

Whenever I use the media apps i.e gallery or any other app like file manager (the apps that require internal storage mostly), the apps close automatically after running like 5 seconds and upon reopening, the contents of app (the media/data that it was displaying) couldn't be found. I have to open them 2 to 3 times and clear it from memory using recent app button (not physical button). Than the contents i.e media show up and again disappear after few seconds and app closes. Chrome runs fine as long as I'm browsing and abruptly closes within 5 seconds when a download is started. Same is in the case of YouTube reddit or any browsing app that I'm using. They [YouTube, reddit, chrome (when not downloading)] run fine for as long as I want. Whatsapp throws an error saying "internal storage is missing" or "turn off USB storage" when downloading or uploading files but downloads media occasionally. Text messages don't throw any error. Just the downloadable files that require internal memory. When I connect the phone to the PC via cable, the PC shows a number of internal storages, ranging from 1 to 20 or more. Depends upon the amount of duration that the phone was connected with PC. Firstly it shows 1 internal storage than keeps on showing more, having same information i.e 35 GB out of 109GB are free on every single one of them, with passage of time. Gallery will first show up as empty and after 1 or two seconds, show the media. The media is readable for few seconds and than the files will say "cannot generate thumbnail" or "cannot play video". I than clear the app from memory using recent apps button and again open it and clear it from memory 2/3 times. Than the media again shows up for 5/10 seconds and is perfectly readable or playable. If I don't clear it from memory, the media also comes back after 5 or 10 seconds and is playable for 5 to 10 seconds. LoL, looks like I'm writing same thing again and again. I don't want to rest until it's the only option (which it is). Infinix note 10 pro (X695), Android. Non rooted. No SD card is put in it. I've tried everything that I could hear or read off. Clearing app cache using adb commands, clearing app data using abd commands (lost xhide data and was signed out of accounts due to this). Making a list of installed packages and using adb command to again install them for user 0. Installing third party virus scanning apps like Microsoft defender mobile (premium) and avast antivirus and avast cleaner app and CCleaner app etc etc etc to clear the hidden caches and scan for viruses. And probably everything that was not the solution for this issue.
