"Incompatible .mpy file" error while using 8.x library version on CircuitPython 8.2.7

Attempting to import adafruit_ssd1306 when using the .mpy file from adafruit-circuitpython-ssd1306-8.x-mpy-2.12.15 with CircuitPython 8.2.7 yields the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "adafruit_ssd1306.py", line 21, in <module>
ValueError: Incompatible .mpy file. Please update all .mpy files. See http://adafru.it/mpy-update for more info.What board? Are you sure it is 8.2? 9.x will produce this error (use the .py file for now w/int.)
Yep, I am sure it is 8.2 (at least, 8.2.7 is what it displays when I enter the REPL). The board is a Seeed Studio XIAO-RP2040.
Line 21 from adafruit_ssd1306 is attempting to import a Micropython library named framebuf.mpy. There is a Circuitpython frame buffer library called adafruit_framebuf.mpy which will be loaded if framebuf.mpy isn't found in either the root folder or the /lib/ folder. It would seem that you have a file called framebuf.mpy on your flash (either root or /lib/) that has an incompatible mpy format.
Which ever version of the framebuf library you attempt to use it must be compiled with a compatible 8.x mpy-cross. I'd recommend you don't have duplicate versions in either the root folder or the /lib/ folder and double check that the version of either framebuf.mpy or adafruit_framebuf.mpy is 8.x (you may actually have to cross compile the Micropython version manually if that's the one you intend to use, I really don't know what's involved in using the Micropython library in Circuitpython).
Actually, it looks to me like this will be solved by installing /lib/adafruit_famebuf.mpy and removing any copies of framebuf.mpy
I suspect the import of framebuf.mpy was intended to allow this library to be used in Micropython, not for the Micropython version of framebuf.mpy to be used in Circuitpython.
framebuf is a native C module in MicroPython (from extmod/modframebuf.c), so there won't be a .mpy file. @cgobat: do you have any file named framebuf.mpy on your CIRCUITPY? If so, where did it come from?
@cgobat I saw a reply from you in my email, but I think you deleted it. Did something change in what you said?
I installed the latest adafruit_ssd1306.mpy on a board running CircuitPython 8.2.7, and could not reproduce the original problem.
Yeah, I replied but then I realized my setup has changed since I opened this issue so I need to do some digging and roll it back to figure out what all I had on my CIRCUITPY at the time.
I've been unable reproduce the setup that was causing this error. I will reopen if it crops up again.
